There are cases when the filesystem will be passed the buffer from a single
read or write call, namely:
1) in 'direct-io' mode (not O_DIRECT), read/write requests don't go
through the page cache, but go directly to the userspace fs
2) currently buffered writes are done with single page requests, but
if Nick's ->perform_write() patch goes it, it will be possible to
do larger write requests. But only if the original write() was
also bigger than a page.
In these cases the filesystem might want to give a hint to the app
about the optimal I/O size.
Allow the userspace filesystem to supply a blksize value to be returned by
stat() and friends. If the field is zero, it defaults to the old
PAGE_CACHE_SIZE value.

Getattr and lookup operations can be running in parallel to attribute changing
operations, such as write and setattr.
This means, that if for example getattr was slower than a write, the cached
size attribute could be set to a stale value.
To prevent this race, introduce a per-filesystem attribute version counter.
This counter is incremented whenever cached attributes are modified, and the
incremented value stored in the inode.
Before storing new attributes in the cache, getattr and lookup check, using
the version number, whether the attributes have been modified during the
request's lifetime. If so, the returned attributes are not cached, because
they might be stale.

This patch set supports large block size(>4k, <=64k) in ext3 just enlarging
the block size limit. But it is NOT possible to have 64kB blocksize on
ext3 without some changes to the directory handling code. The reason is
that an empty 64kB directory block would have a rec_len == (__u16)2^16 ==
0, and this would cause an error to be hit in the filesystem. The proposed
solution is treat 64k rec_len with a an impossible value like rec_len =
0xffff to handle this.
The Patch-set consists of the following 2 patches.
[1/2] ext3: enlarge blocksize
- Allow blocksize up to pagesize
[2/2] ext3: fix rec_len overflow
- prevent rec_len from overflow with 64KB blocksize
Now on 64k page ppc64 box runs with this patch set we could create a 64k
block size ext3, and able to handle empty directory block.
