socket: Remove redundant in_lock in incoming message handling

2018-12-26T05:15:08+00:00

A given epoll thread can handle only one incoming (POLLIN) request.
And until the socket is rearmed for listening, it is guaranteed that
there won't be any new incoming requests. As a result, the priv->in_lock
which guards the socket proto state machine seems redundant.

This patch removes priv->in_lock.

gfapi: Access fs->oldvolfile under mutex lock

2018-12-25T17:36:01+00:00

In some cases (for eg., when there are multiple
RPC_CLNT_CONNECT notifications), multiple threads may fetch
volfile and try to update it in 'fs' object simultaneously.
Hence protect those variables' access under fs->mutex lock.

tests: Brick is getting OOM in ./tests/bugs/core/bug-1432542-mpx-restart-crash.t

2018-12-21T07:41:33+00:00

This test "tests/bugs/core/bug-1432542-mpx-restart-crash.t" case creates 20 2x3
volumes after enabling brick_mux.At the time of creating last volume brick is getting
OOM because brick consumption has increased from previous consumption due to these patches
https://review.gluster.org/#/c/glusterfs/+/19997/,
https://review.gluster.org/#/c/glusterfs/+/20362/

To avoid OOM reduce NUM_VOLS to 15 so that brick consumption has reduced

rpc: Use adaptive mutex in rpcsvc_program_register

2018-12-20T16:44:26+00:00

Adaptive mutexes are used to protect critical/shared data items that
are held for short periods.It provides a balance between spin locks
and traditional mutex.We have observed after use adaptive mutex in
rpcsvc_program_register got some improvement.
