Subject: [RHEL 5.1 PATCH] dm multipath: rr path order is inverted
Date: Thu, 10 May 2007 10:52:56 +0200
Bugzilla: 239643
Message-Id: <4642DD68.6050906@redhat.com>
Changelog: [md] dm multipath: rr path order is inverted


RHEL5.1 dm multipath: round-robin path order is inverted
Resolves: rhbz#239643
Patch is upstream and in RHEL4.5.

When adding paths to the round-robin path selector, their order gets
inverted, which is not desirable.

Fix by replacing list_add() with list_add_tail().
