Hi Chris,
Please consider the following fixes for the 4.3 kernel release candidates.
One of them addresses a deadlock introduced in 4.3, another is for a false
enospc condition (which I introduced in a 4.2 commit) that can happen either
on empty filesystems or filesystems with files having only inlined extents
after mounting with "-o nospace_cache", a fix for read corruption of
compressed and shared (cloned, deduped) extents that has been present
possibly since the compression feature exists or since the clone/dedup
ioctls exist, and finally, from Jeff, a fix for a long standing null
pointer dereference during inode eviction that some users were running
into very often.
They are all short and simple, the read corruption one is bigger only
because it adds a big fat comment, and just like Jeff's fix, it was
tagged for backporting to stable releases too.
I included any Reviewed-by tags people added through the mailing list and
two of these fixes have corresponding test cases for fstests that were
submitted, along with the respective fixes, to the mailing list.
Thanks.
