Hi Linus,
Could you consider these three fixes for 6.13-rc4?
The first one fixes a syzbot UAF report caused by a commit introduced
in this cycle, but it also addresses a longstanding memory leak. The
second one resolves a PSI memstall mis-accounting issue.
The remaining patches switch file-backed mounts to use buffered I/Os
by default instead of direct I/Os, since the page cache of underlay
files is typically valid and maybe even dirty. This change also aligns
with the default policy of loopback devices. A mount option has been
added to try to use direct I/Os explicitly.
All commits have been in -next and no potential merge conflict
is observed.
Thanks,
Gao Xiang
