(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 The patches can also be found here: https://git.kernel.org/pub/scm/linux/kernel/git/dhowells/linux-fs.git/log/?h=netfs-fixes Thanks, David David Howells (4): mm: Fix missing folio invalidation calls during truncation afs: Fix post-setattr file edit to do truncation correctly netfs: Fix netfs_release_folio() to say no if folio dirty netfs: Fix trimming of streaming-write folios in netfs_inval_folio() fs/afs/inode.c | 11 +++++++--- fs/netfs/misc.c | 53 +++++++++++++++++++++++++++++++++++-------------- mm/truncate.c | 4 ++-- 3 files changed, 48 insertions(+), 20 deletions(-)
