Vladimir Sementsov-Ogievskiy d1fdf257d5 nbd: rename read_sync and friends ... Rename nbd_wr_syncv -> nbd_rwv read_sync -> nbd_read read_sync_eof -> nbd_read_eof write_sync -> nbd_write drop_sync -> nbd_drop 1. nbd_ prefix read_sync and write_sync are already shared, so it is good to have a namespace prefix. drop_sync will be shared, and read_sync_eof is related to read_sync, so let's rename them all. 2. _sync suffix _sync is related to the fact that nbd_wr_syncv doesn't return if a write to socket returns EAGAIN. The first implementation of nbd_wr_syncv (was wr_sync in 7a5ca8648b) just loops while getting EAGAIN, the current implementation yields in this case. Why we want to get rid of it: - it is normal for r/w functions to be synchronous, so having an additional suffix for it looks redundant (contrariwise, we have _aio suffix for async functions) - _sync suffix in block layer is used when function does flush (so using it for other thing is confusing a bit) - keep function names short after adding nbd_ prefix 3. for nbd_wr_syncv let's use more common notation 'rw' Reviewed-by: Eric Blake <eblake@redhat.com> Signed-off-by: Vladimir Sementsov-Ogievskiy <vsementsov@virtuozzo.com> Message-Id: <20170602150150.258222-2-vsementsov@virtuozzo.com> Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>		2017-06-15 11:04:06 +02:00
