Patches in the vfs.fixes branch should appear in linux-next soon. Please report any outstanding bugs that were missed during review in a new review to the original patch series allowing us to drop it.

Hi Christian, Steve, Firstly, there are some fixes for truncation, netfslib and afs that I discovered whilst trying Pankaj Raghav's minimum folio order patchset: (1) Fix truncate to make it honour AS_RELEASE_ALWAYS in a couple of places that got missed. (2) Fix duplicated editing of a partially invalidated folio in afs's post-setattr edit phase. (3) Fix netfs_release_folio() to indicate that the folio is busy if the folio is dirty (as does iomap). (4) Fix the trimming of a folio that contain streaming-write data when truncation occurs into or past that folio Here's a patch to netfs for short reads: (5) Fix netfslib's short read retry to reset the buffer iterator otherwise the wrong part of the buffer may get written on. Here are a couple of fixes to DIO read handling and the retrying of reads, particularly in relation to cifs. They have both had some fixes to the fixes rolled in: (6) Fix the missing credit renegotiation in cifs on the retrying of reads. The credits we had ended with the original read (or the last retry) and to perform a new read we need more credits otherwise the server can reject our read with EINVAL. (7) Fix the handling of short DIO reads to avoid ENODATA when the read retry tries to access a portion of the file after the EOF. Here's a fix for hole punching in cifs: (8) Fix cifs FALLOC_FL_PUNCH_HOLE support as best I can. If it's going to punch a hole in dirty data in the pagecacne, invalidating that data may result in the EOF not being moved correctly. The set-zero and the eof-move RPC ops really need compounding to avoid third-party interference. And finally, here's an adjustment to debugging statements: (9) Adjust three debugging output statements. Not strictly a fix, so could be dropped. Including the subreq ID in some extra debug lines helps a bit, though. The patches can also be found here: https://git.kernel.org/pub/scm/linux/kernel/git/dhowells/linux-fs.git/log/?h=netfs-fixes They're on top of part of Christian's vfs.fixes tree, including the partial reversion of the commit to replace PG_fscache.
