Hi Christian,

Here 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

The patches can also be found here:

Thanks,
David
