[dm-devel] [PATCH 0/4] discard updates

[Mikulas Patocka <mpatocka redhat com>]

Hi

Here are update patches for Mike's discard.

The first two patches bugfixes, they should be certainly applied to RHEL6.

The third patch supports discards on composite devices --- it could be 
considered a "bugfix" if not sending discards is considered a "bug". I 
think it still can go to RHEL6.

The fourth patch is an enhancement to support discard if only some of the 
underlying devices support it.
