cluster/afr: Allocate diff algorithm loop_state structures only once.

2009-12-28T12:39:24+00:00

Instead of CALLOC'ing a loop_state structure at the beginning
of every loop, keep a table of allocated structures and reuse
them.

afr: fix logic to break out of diff/checksum loop

2009-11-29T05:30:10+00:00

When checksum fop returns error, mark for terminating the loop at the end
of the iteration (when all checksum calls of that iteration return) and
not immediately

cluster/afr: Bail out of the self-heal driver loops as soon as possible

2009-11-03T16:16:54+00:00

Don't wait for the next recursive call to sh_{full,diff}_loop_driver
to decide that we've reached the end of file, as the frame could
have been destroyed by that time (if subvolumes are posix).

of the "diff" data self-heal algorithm simultaneously.
