Log Message:
ftruncate(2) cause a SETATTR with only va_size set, and some filesystems
(e.g.: glusterfs) will do a custom handling in such a situation. This
breaks because libpuffs folds a metadata (va_atime and va_mtime) update
in each SETATTR. We try to identify SETATTR caused by ftruncate(2) and
remove va_atime and va_mtime in such situation.
This fixes a bug with glusterfs, where parts of a file downloaded by
FTP was filled with zeros because of a ftruncate(2) sent out of order
with write(2) requests. glusterfs behavior depends on the undocumented
FUSE rule that ftruncate(2) will only set va_size in SETATTR.
