Subject[GIT PULL] gfs2 fixes
Date
Hi Linus,

we've finally identified commit dc732906c245 ("gfs2: Introduce flag for glock
holder auto-demotion") to be the other cause of the filesystem corruption we've
been seeing. This feature isn't strictly necessary anymore, so we've decided
to stop using it for now. With this and the gfs_iomap_end rounding fix you've
already seen ("gfs2: Fix filesystem block deallocation for short writes" in
this pull request), we're corruption free again now.

Would you like to still pull these fixes for v5.18, or should we send them in
the next merge window?

Thanks again for all the help you've provided.

Andreas
