* features/locks: Fix statedump codePranith Kumar K2012-08-131-0/+4
| | | | | | | | | | | | | | | | | | | | | | | | RCA: Taking blocking mutex/spin locks lead to dead locks because of the locking order in statedumps. Also we were asked to remove gf_logs if possible to avoid extra cost in signal handlers. Fix: changed blocking mutes/spin locks to their non-blocking variants. Removed gf_logs in locks xlator statedump code-path. Tests: State-dump success cases are working fine. Triggered try-lock failures by putting statedumps in a while loop. In parallel did chown of the same file in a while loop.

* features/locks: Implement release xlator callback.Pavan Sondur2009-12-061-0/+3
| | | | | | | | | | | | This patch solves the lock bailout problem seen recently when autoconf tools were run. This is a workaround, where 'flock' locks are removed in pl_release, if an explicit UNLCK call does not come. The complete fix would be to allow 'fcntl' and 'flock' locks to operate in different domains. Signed-off-by: Pavan Vilas Sondur <pavan@gluster.com> Signed-off-by: Anand V.
