features/shard: Make o-direct writes work with sharding

2016-04-11T19:48:53+00:00

With files opened with o-direct, the expectation is that
the IO performed on the fds is byte aligned wrt the sector size
of the underlying device. With files getting sharded, a single
write from the application could be broken into more than one write
falling on different shards which _might_ cause the original byte alignment
property to be lost. To get around this, shard translator will send fsync
on odirect writes to emulate o-direct-like behavior in the backend.

shard: add seek() FOP as not supported

2016-02-04T17:29:50+00:00

For getting basic support for SEEK_DATA/SEEK_HOLE, sharding has not been
implemented. Bug 1301647 has been filed to get this new feature in
sharding as well.

Because of a premature merge (and revert), this change is re-applying
everything from commit 2ce3daa94066dcc77cdc6b54a31747b6c7c0c2fc again.
