[Ocfs2-devel] add error check for ocfs2_read_locked_inode() call

[Oleg Gawriloff]

After upgrading from 2.6.28.10 to 2.6.29.3 I've saw following new errors 
in kernel log:
May 12 14:46:41 falcon-cl5
May 12 14:46:41 falcon-cl5 (6757,7):ocfs2_read_locked_inode:466 ERROR: 
status = -22

Only one node is mounted volumes in cluster:
/dev/sde on /home/apache/users/D1 type ocfs2 
(rw,_netdev,noatime,heartbeat=local)
/dev/sdd on /home/apache/users/D2 type ocfs2 
(rw,_netdev,noatime,heartbeat=local)
/dev/sdc on /home/apache/users/D3 type ocfs2 
(rw,_netdev,noatime,heartbeat=local)
The error appears multiple times per second and only numbers is different.

What does it means, any suggestions?
