* features/locks : Improves debuggability of inode/entry locks.Anuradha Talur2013-09-031-5/+8
| | | | | | | | | | | | | | | | | Prints, in the statedump, the information about the mount that performed the inode/entry lk. For the entrylks that are granted after a blocked state, the blocked time is not printed. A patch for that will be sent later.

* locks: Added an xdata-based 'cmd' for inodelk count in a given domainshishir gowda2013-07-181-2/+2
| | | | | | | | | | | | | | | | | | | | Following is the semantics of the 'cmd': 1) If @domain is NULL - returns no. of locks blocked/granted in all domains 2) If @domain is non-NULL- returns no. of locks blocked/granted in that domain 3) If @domain is non-existent - returns '0'; This is important since locks xlator creates a domain in a lazy manner. where @domain - a string representing the domain.

* features/locks: Fix statedump codePranith Kumar K2012-07-291-0/+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.

| | | | | | | | | | | | 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.
