[patch 098/108] dm exception store: fix exstore lookup to be case insensitive

[Greg KH]

2.6.30-stable review patch.  If anyone has any objections, please let us know.

------------------

From: Jonathan Brassow <jbrassow@xxxxxxxxxx>

commit f6bd4eb73cdf2a5bf954e497972842f39cabb7e3 upstream.

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

This patch makes the code case insensitive as intended and fixes some
regressions reported with device-mapper snapshots.
