net: don't record/verify UDP sequence numbers if buffer is too small
(2015-01-16 18:26:37 -0700)
----------------------------------------------------------------
Jens Axboe (6):
Improve precision of the io_limit setting
ioengine: if we get BUSY in queuing, adjust accounting
verify: always check completion list for low depth verifies
sha256: fix verify failure
Fix segfault with client/server and minimal output
crc/test: sha1 should do _final() after _update()
