[lvm-devel] [PATCH 0 of 4] Re-integrate a failed secondary mirror leg

[Malahal Naineni]

The following 4 patches try to re-integrate a failed secondary mirror leg.

Patch 1: Re-arranges some code and introduces more error type returns
Patch 2: Tries to re-integrate the failed device indefinitely
Patch 3: Removes some "#ifdef 0' code and fixes timeout setup mechanism.
         Also adds interface to remove a timeout setup
Patch 4: Uses Patch 2 and Patch 3 to attempt only few times at a regular
         interval to resync the failed mirror.

Tested with flakey dm module!
