features/locks: Do not try to set values in dictionary when lookup has failed

2009-10-31T14:14:10+00:00

lock-count was being set without checking for op_ret from lookup. This would
cause a lot of Critical messages in the log as dict would be NULL in case
of a lookup failure.

Also, did some minor re-factoring.

cluster/afr: Don't try to self-heal if there are locks held

2009-10-30T11:30:59+00:00

If the inodelk_count or entrylk_count is positive on a
file/directory, don't try to do self-heal on it.

2009-10-29T19:02:50+00:00

Hold a lock on the inode for the getxattr/add-array/setxattr
section since multiple threads can enter into it causing
wrong values to be written and triggering spurious replicate
self-heal later.

cluster/afr: Prevent spurious entry self-heal.

2009-10-23T12:54:57+00:00

If the initial lookup shows that 'pending' is positive, then
self-heal will hold a lock and do a lookup again. This lookup
might show that 'pending' is zero everywhere. However, entry
self-heal used to consider this as a case of 'no sources' and
try to merge the directories. This patch checks for that case
and does not do the merge.
