[dm-devel] [PATCH 1 of 1] dm exception store: exstore type lookup should be case insensitive

[Jonathan Brassow]

This two line patch will fix the regressions some users are experiencing

When snapshots are created using 'p' instead of 'P' as the
exception store type, the device-mapper table loading would
fail.

This patch allows the code to be case insensitive.
