[PATCHSET V2] block/xfs: bdev page cache bug fixes for 6.15

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hi all,

Here are a handful of bugfixes for 6.15.  The first patch fixes a race
between set_blocksize and block device pagecache manipulation; the rest
removes XFS' usage of set_blocksize since it's unnecessary.

If you're going to start using this code, I strongly recommend pulling
from my git trees, which are linked below.

With a bit of luck, this should all go splendidly.
Comments and questions are, as always, welcome.
