replicate: remove checks which prevented self-heal when open fds were present

2010-10-18T10:25:50+00:00

this check is not needed anymore since the introduction of changelog piggybacking
as the optimization technique instead of first-write-to-flush technique

replicate: replace first-write-to-flush optimization

optimization and do other cleanups (removal of post-post-op hook etc.)

cluster/afr: Set lk-owner to pid when fuse does not supply it.

2010-06-29T09:58:04+00:00

Use the frame->root address as lk-owner when FUSE does
not supply lk_owner.

Raghu,
I unit tested this patch with dbench and self heal tests.
Did not observe lk-owner=0 in any server logs. Can you
verify this patch with the other tests you had run today?

cluster/afr: Check before accessing xattrs in data self heal.

The lookup xattrs might be null, because a lookup might not have been issued during self heal,
especially if only data self heal is required.
