io_u: Support fsync for --rw=trimwrite
Browse files Browse the repository at this point in the history
Even if ddir is determined in get_rw_ddir(), ddir might be updated in
set_rw_ddir().  if td represents trimwrite, it will be updated to either
DDIR_TRIM or DDIR_WRITE even ddir already represents for DDIR_SYNC.

To support DDIR_SYNC(fsync) for trimwrite, this patch checks ddir_sync()
in case of trimwrite not to update the pre-determined ddir.
