As inode table blocks are contiguous, inode table blocks inside the
block_group can be represented as range [itbl_cluster_start,
itbl_cluster_last]. Then we can simply account inode table cluters and
check cluster overlap with [itbl_cluster_start, itbl_cluster_last]
instead of traverse each block of inode table.
By the way, this patch fixes code style problem of comment for
ext4_num_overhead_clusters.

ext4_num_base_meta_clusters is already aware of meta_bg feature and test
if block_group is inside real meta block groups before calling
ext4_bg_num_gdb. Then ext4_bg_num_gdb will check if block group is inside
a real meta block groups again to decide either ext4_bg_num_gdb_meta or
ext4_bg_num_gdb_nometa is needed.
Call ext4_bg_num_gdb_meta or ext4_bg_num_gdb_nometa directly after we
check if block_group is inside a meta block groups in
ext4_num_base_meta_clusters to remove redundant check of meta block
groups in ext4_bg_num_gdb.

Test generic/390 in data=journal mode often triggers a warning that
ext4_do_writepages() tries to start a transaction on frozen filesystem.
This happens because although all dirty data is properly written, jbd2
checkpointing code writes data through submit_bh() and as a result only
buffer dirty bits are cleared but page dirty bits stay set. Later when
the filesystem is frozen, writeback code comes, tries to write
supposedly dirty pages and the warning triggers. Fix the problem by
calling sync_filesystem() once more after flushing the whole journal to
clear stray page dirty bits.

Add support for writeback of journalled data directly into
ext4_writepages() instead of offloading it to write_cache_pages(). This
actually significantly simplifies the code and reduces code duplication.
For checkpointing of committed data we can use ext4_writepages()
rightaway the same way as writeback of ordered data uses it on
transaction commit. For journalling of dirty mapped pages, we need to
add a special case to mpage_prepare_extent_to_map() to add all page
buffers to the journal.

In case mpage_submit_page() returns error, it doesn't really matter
whether we call mpage_page_done() and then return error or whether we
return directly because in that case page cleanup will be done by
mpage_release_unused_pages() instead. Logically, it makes more sense to
leave the cleanup to mpage_release_unused_pages() because we didn't
succeed in writing the page. So move mpage_page_done() calls after the
error handling.

Move page unlocking during page writeback out of mpage_submit_page()
into the callers. This will allow writeback in data=journal mode to keep

In data=journal mode, page should be dirtied only when it has buffers
for checkpoint or it is writeably mapped. In the first case, we don't
need to do anything special. In the second case, page was already added
to the journal by ext4_page_mkwrite() and since transaction commit
writeprotects mapped pages again, page should be writeable (and thus
dirtied) only while it is part of the running transaction. So nothing
needs to be done either. The only special case is when someone pins the
page and uses this pin for modifying page data. So recognize this
special case and only then mark the page as having data that needs
adding to the journal.

Pull misc fixes from Al Viro:
"pick_file() speculation fix + fix for alpha mis(merge,cherry-pick)
The fs/file.c one is a genuine missing speculation barrier in
pick_file() (reachable e.g. via close(2)). The alpha one is strictly
speaking not a bug fix, but only because confusion between
preempt_enable() and preempt_disable() is harmless on architecture
without CONFIG_PREEMPT.
Looks like alpha.git picked the wrong version of patch - that braino
used to be there in early versions, but it had been fixed quite a
while ago..."

Pull btrfs fixes from David Sterba:
"First batch of fixes. Among them there are two updates to sysfs and
ioctl which are not strictly fixes but are used for testing so there's
no reason to delay them.
- fix block group item corruption after inserting new block group
- fix extent map logging bit not cleared for split maps after
dropping range
- fix calculation of unusable block group space reporting bogus
values due to 32/64b division
- fix unnecessary increment of read error stat on write error
- improve error handling in inode update
- export per-device fsid in DEV_INFO ioctl to distinguish seeding
devices, needed for testing
- allocator size classes:
- fix potential dead lock in size class loading logic
- print sysfs stats for the allocation classes"

A user should be allowed to take out a lease via an idmapped mount if
the fsuid matches the mapped uid of the inode. generic_setlease() is
checking the unmapped inode uid, causing these operations to be denied.
Fix this by comparing against the mapped inode uid instead of the
unmapped uid.
