performance/md-cache: purge cache on ENOENT/ESTALE errors

2018-04-25T07:01:17+00:00

If not, next lookup could be served from cache and can be success,
which is wrong. This can affect retry logic of VFS when it receives an
ESTALE.

gluster: Sometimes Brick process is crashed at the time of stopping brick

2018-04-19T04:31:51+00:00

Problem: Sometimes brick process is getting crashed at the time
         of stop brick while brick mux is enabled.

Solution: Brick process was getting crashed because of rpc connection
          was not cleaning properly while brick mux is enabled.In this patch
          after sending GF_EVENT_CLEANUP notification to xlator(server)
          waits for all rpc client connection destroy for specific xlator.Once rpc
          connections are destroyed in server_rpc_notify for all associated client
          for that brick then call xlator_mem_cleanup for for brick xlator as well as
          all child xlators.To avoid races at the time of cleanup introduce
          two new flags at each xlator cleanup_starting, call_cleanup.

      with same patch after enable brick mux forcefully, all test cases are
      passed.
