cluster/ec: Provide an option to enable/disable eager lock
Problem: If a fop takes lock, and completes its operation, it waits for 1 second before releasing the lock. However, If ec find any lock contention within this time period, it release the lock immediately before time expires. As we take lock on first brick, for few operations, like read, it might happen that discovery of lock contention might take long time and can degrades the performance. Solution: Provide an option to enable/disable eager lock. If eager lock is disabled, lock will be released as soon as fop completes. gluster v set <VOLUME NAME> disperse.eager-lock on gluster v set <VOLUME NAME> disperse.eager-lock off master- http://review.gluster.org/13605 Change-Id: I000985a787eba3c190fdcd5981dfbf04e64af166 BUG: 1318965 Signed-off-by: Ashish Pandey <aspandey@redhat.com> Reviewed-on: http://review.gluster.org/13773 Smoke: Gluster Build System <jenkins@build.gluster.com> CentOS-regression: Gluster Build System <jenkins@build.gluster.com> NetBSD-regression: NetBSD Build System <jenkins@build.gluster.org> Reviewed-by: Pranith Kumar Karampuri <pkarampu@redhat.com>
