Alasdair G Kergon 76df1c651b [PATCH] device-mapper snapshot: fix invalidation ... When a snapshot becomes invalid, s->valid is set to 0. In this state, a snapshot can no longer be accessed. When s->lock is acquired, before doing anything else, s->valid must be checked to ensure the snapshot remains valid. This patch eliminates some races (that may cause panics) by adding some missing checks. At the same time, some unnecessary levels of indentation are removed and snapshot invalidation is moved into a single function that always generates a device-mapper event.
