rdma: pre-register iobuf_pool with rdma devices.

2015-03-27T11:34:08+00:00

        Back port pf : http://review.gluster.org/9506

registring buffers with rdma device is a time consuming
operation. So performing registration in code path will
decrease the performance.
Using a pre registered memory will give a bettor performance,
ie, register iobuf_pool during rdma initialization. For
dynamically created arena, we can register with all the
device.

rdma: post multiple work request in a single call.

        Back port of : http://review.gluster.org/9327

ibv_post-send will allow to send multiple work request
in a single call posting as linked list.

So if the payload count > 1, we can perform the data
operation in a single call to ibv_post_send.

Having this particular check which was introduced by
commit c57c455347a72ebf0085add49ff59aae26c7a70d causes a drop in
performance in readdirp. So the behavior is made configurable with this
patch.

NetBSD portability fix: recover errno on runner error

2015-02-04T12:06:45+00:00

Some time ago we introduced F_CLOSEM to efficiently close unused
file descriptors when using a runner. But since it also close the
file descriptor used to send back errno to glusterd, it got unable
to detect an error on execve().

Fix this by backing out F_CLOSEM usage.

inode: Handle '/' in basename in inode_link/unlink

2014-11-17T07:36:42+00:00

        Backport of http://review.gluster.org/9004

Problem:
inode_link is sometimes called with a trailing '/'. Lookup, dentry
operations like link/unlink/mkdir/rmdir/rename etc come without trailing
'/' so the stale dentry with '/' remains in the dentry list of the inode.

Fix:
Add assert checks and return NULL for '/' in bname.
Fix ancestry building code to call without '/' at the end.
