Yes, that was my next question..
While you're at it adding a command why we are doing
the sync would also be really useful, and having it in just one place
helps with that.
ok, there was such comment in xfs_preflush_devices().
@Darrick, please comment on whether happy with changes discussed.
I put the sync_blockdev calls in a separate function so that the
EIO/ENOSPC/whatever errors that come from the block device sync don't
get morphed into ENOMEM by xfs_alloc_buftarg before being passed up. I
suppose we could make that function return an ERR_PTR, but I was trying
to avoid making even more changes at the last minute, again.
It seems simpler to just have the individual sync_blockdev() calls from
xfs_alloc_buftarg(), rather than adding ERR_PTR() et al handling in both
xfs_alloc_buftarg() and xfs_open_devices().
