[GIT PULL] xfs: fixes for v4.20-rc6

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

 



Hi Linus,

Here are hopefully the last set of fixes for 4.20.  There's a fix for a
longstanding statfs reporting problem with project quotas, a correction
for page cache invalidation behaviors when fallocating near EOF, and a
fix for a broken metadata verifier return code.

Finally, the most important fix is to the pipe splicing code (aka the
generic copy_file_range fallback) to avoid pointless short directio
reads by only asking the filesystem for as much data as there are
available pages in the pipe buffer.  Our previous fix (simulated short
directio reads because the number of pages didn't match the length of
the read requested) caused subtle problems on overlayfs, so that part is
reverted.

Anyhow, this series passes fstests -g all on xfs and overlay+xfs, and
has passed 17 billion fsx operations problem-free since I started
testing; and merges cleanly with master as of last night, so please let
me know if you encounter problems.
