[dm-devel] [PATCH 0/4] Fix corruption of snapshot store on invalidation

[Mikulas Patocka <mpatocka redhat com>]

Hi

These four patches fix snapshot store corruption on snapshot invalidation.
(bug https://bugzilla.redhat.com/show_bug.cgi?id=461506)

The first two patches fix a race causing corruption of snapshot store 
header.

The second two patches fix a crash when the snapshot is activated with 
corrupted store. With the patches applied, error is reported instead of a 
crash and the volume is not activated.
