[0/2] zonefs: use zone-append for aio with rwf append

Message

Johannes Thumshirn July 20, 2020, 1:21 p.m. UTC

When an asynchronous I/O, that has the RWF_APPEND flag set, get's submitted
to a sequential zone-file in zonefs, issue this I/O using REQ_OP_ZONE_APPEND.

On a successful write, the location the data has been written to is returned
in AIOs res2 field.

This series has no regressions to current zonefs-tests and specific tests will
be introduced as well.
