The comment for count_range_bits() mentions that the search is fast if we
are asking for a range with the EXTENT_DIRTY bit set. However that is no
longer true since we don't use that bit and the optimization for that was
removed in:
commit 71528e9e16 ("btrfs: get rid of extent_io_tree::dirty_bytes")
So remove that part of the comment mentioning the no longer existing
optimized case, and, while at it, add proper documentation describing the
purpose, arguments and return value of the function.

An inode's io_tree can be quite large and there are cases where due to
delalloc it can have thousands of extent state records, which makes the
red black tree have a depth of 10 or more, making the operation of
count_range_bits() slow if we repeatedly call it for a range that starts
where, or after, the previous one we called it for. Such use cases are
when searching for delalloc in a file range that corresponds to a hole or
a prealloc extent, which is done during lseek SEEK_HOLE/DATA and fiemap.
So introduce a cached state parameter to count_range_bits() which we use
to store the last extent state record we visited, and then allow the
caller to pass it again on its next call to count_range_bits(). The next
patches in the series will make fiemap and lseek use the new parameter.
This change is part of a patchset that has the goal to make performance
better for applications that use lseek's SEEK_HOLE and SEEK_DATA modes to
iterate over the extents of a file. Two examples are the cp program from
coreutils 9.0+ and the tar program (when using its --sparse / -S option).

During lseek (SEEK_HOLE/DATA) and fiemap, when processing a file range
that corresponds to a hole or a prealloc extent, we have to check if
there's any delalloc in the range. We do it by searching for delalloc
ranges in the inode's io_tree (for unflushed delalloc) and in the inode's
extent map tree (for delalloc that is flushing).
We avoid searching the extent map tree if the number of outstanding
extents is 0, as in that case we can't have extent maps for our search
range in the tree that correspond to delalloc that is flushing. However
if we have any unflushed delalloc, due to buffered writes or mmap writes,
then the outstanding extents counter is not 0 and we'll search the extent
map tree. The tree may be large because it can have lots of extent maps
that were loaded by reads or created by previous writes, therefore taking
a significant time to search the tree, specially if have a file with a
lot of holes and/or prealloc extents.
We can improve on this by instead of searching the extent map tree,
searching the ordered extents tree of the inode, since when delalloc is
flushing we create an ordered extent along with the new extent map, while
holding the respective file range locked in the inode's io_tree. The
ordered extents tree is typically much smaller, since ordered extents have
a short life and get removed from the tree once they are completed, while
extent maps can stay for a very long time in the extent map tree, either
created by previous writes or loaded by read operations.
So use the ordered extents tree instead of the extent maps tree.

better for applications that use lseek's SEEK_HOLE and SEEK_DATA modes to

During fiemap and lseek (SEEK_HOLE/DATA), when looking for delalloc in a
range corresponding to a hole or a prealloc extent, if we found the whole
range marked as delalloc in the inode's io_tree, then we can terminate
immediately and avoid searching the extent map tree. If not, and if the
found delalloc starts at the same offset of our search start but ends
before our search range's end, then we can adjust the search range for
the search in the extent map tree. So implement those changes.

We don't need to set the EXTENT_UPDATE bit in an inode's io_tree to mark a
range as uptodate, we rely on the pages themselves being uptodate - page
reading is not triggered for already uptodate pages. Recently we removed
most use of the EXTENT_UPTODATE for buffered IO with commit 52b029f427
("btrfs: remove unnecessary EXTENT_UPTODATE state in buffered I/O path"),
but there were a few leftovers, namely when reading from holes and
successfully finishing read repair.
These leftovers are unnecessarily making an inode's tree larger and deeper,
slowing down searches on it. So remove all the leftovers.

[BACKGROUND]
Although both btrfs metadata and data has their read time verification
done at endio time (btrfs_validate_metadata_buffer() and
btrfs_verify_data_csum()), metadata has extra verification, mostly
parentness check including first key/transid/owner_root/level, done at
read_tree_block() and btrfs_read_extent_buffer().
On the other hand, all the data verification is done at endio context.
[ENHANCEMENT]
This patch will make a new union in btrfs_bio, taking the space of the
old data checksums, thus it will not increase the memory usage.
With that extra btrfs_tree_parent_check inside btrfs_bio, we can just
pass the check parameter into read_extent_buffer_pages(), and before
submitting the bio, we can copy the check structure into btrfs_bio.
And finally at endio time, we can grab btrfs_bio::parent_check and pass
it to validate_extent_buffer(), to move the remaining checks into it.
This brings the following benefits:
- Much simpler btrfs_read_extent_buffer()
Now it only needs to iterate through all mirrors.
- Simpler read-time transid check
Previously we go verify_parent_transid() after reading out the extent
buffer.
Now the transid check is done inside the endio function, no other
code can modify the content.
Thus no need to use the extent lock anymore.

There are several different tree block parentness check parameters used
across several helpers:
- level
Mandatory
- transid
Under most cases it's mandatory, but there are several backref cases
which skips this check.
- owner_root
- first_key
Utilized by most top-down tree search routine. Otherwise can be
skipped.
Those four members are not always mandatory checks, and some of them are
the same u64, which means if some arguments got swapped compiler will
not catch it.
Furthermore if we're going to further expand the parentness check, we
need to modify quite some helpers just to add one more parameter.
This patch will concentrate all these members into a structure called
btrfs_tree_parent_check, and pass that structure for the following
helpers:
- btrfs_read_extent_buffer()
- read_tree_block()

There is a repeating code section in the parent function after calling
btrfs_alloc_device(), as below:
name = rcu_string_strdup(path, GFP_...);
if (!name) {
btrfs_free_device(device);
return ERR_PTR(-ENOMEM);
}
rcu_assign_pointer(device->name, name);
Except in add_missing_dev() for obvious reasons.
This patch consolidates that repeating code into the btrfs_alloc_device()
itself so that the parent function doesn't have to duplicate code.
This consolidation also helps to review issues regarding RCU lock
violation with device->name.
Parent function device_list_add() and add_missing_dev() use GFP_NOFS for
the allocation, whereas the rest of the parent functions use GFP_KERNEL,
so bring the NOFS allocation context using memalloc_nofs_save() in the
function device_list_add() and add_missing_dev() is already doing it.

Since all the recovery paths have been migrated to the new error bitmap
based system, we can remove the old stripe number based system.
This cleanup involves one behavior change:
- Rebuild rbio can no longer be merged
Previously a rebuild rbio (caused by retry after data csum mismatch)
can be merged, if the error happens in the same stripe.
But with the new error bitmap based solution, it's much harder to
compare error bitmaps.
So here we just don't merge rebuild rbio at all.
This may introduce some performance impact at extreme corner cases,
but we're willing to take it.
Other than that, this patch will cleanup the following members:
- rbio::faila
- rbio::failb
They will be replaced by per-vertical stripe check, which is more
accurate.
- rbio::error
It will be replace by per-vertical stripe error bitmap check.
- Allow get_rbio_vertical_errors() to accept NULL pointers for
@faila and @failb
Some call sites only want to check if we have errors beyond the
tolerance.

Since we have rbio::error_bitmap to indicate exactly where the errors
are (including read error and csum mismatch error), we can make recovery
path more accurate.
For example:
0 32K 64K
Data 1 |XXXXXXXX| |
Data 2 | |XXXXXXXXX|
Parity | | |
1) Get csum mismatch when reading data 1 [0, 32K)
2) Mark corresponding range error
The old code will mark the whole data 1 stripe as error.
While the new code will only mark data 1 [0, 32K) as error.
3) Recovery path
The old code will recover data 1 [0, 64K), all using Data 2 and
parity.
This means, Data 1 [32K, 64K) will be corrupted data, as data 2
[32K, 64K) is already corrupted.
While the new code will only recover data 1 [0, 32K), as only
that range has error so far.
This new behavior can avoid populating rbio cache with incorrect data.

Currently btrfs raid56 uses btrfs_raid_bio::faila and failb to indicate
which stripe(s) had IO errors.
But that has some problems:
- If one sector failed csum check, the whole stripe where the corruption
is will be marked error.
This can reduce the chance we do recover, like this:
0 4K 8K
Data 1 |XX| |
Data 2 | |XX|
Parity | | |
In above case, 0~4K in data 1 should be recovered using data 2 and
parity, while 4K~8K in data 2 should be recovered using data 1 and
parity.
Currently if we trigger read on 0~4K of data 1, we will also recover
4K~8K of data 1 using corrupted data 2 and parity, causing wrong
result in rbio cache.
- Harder to expand for future M-N scheme
As we're limited to just faila/b, two corruptions.
- Harder to expand to handle extra csum errors
This can be problematic if we start to do csum verification.
This patch will introduce an extra @error_bitmap, where one bit
represents error that happened for that sector.
The choice to introduce a new error bitmap other than reusing
sector_ptr, is to avoid extra search between rbio::stripe_sectors[] and
rbio::bio_sectors[].
Since we can submit bio using sectors from both sectors, doing proper
search on both array will more complex.
Although the new bitmap will take extra memory, later we can remove
things like @error and faila/b to save some memory.
Currently the new error bitmap and failab mechanism coexists, the error
bitmap is only updated at endio time and recover entrance.
