Subject: [PATCH] lmLogOpen() broken failure exit
Date: Sun, 5 Jun 2011 19:22:56 +0100 [thread overview]
Message-ID: <20110605182256.GG11521@ZenIV.linux.org.uk> (raw)
Callers of lmLogOpen() expect it to return -E... on failure exits, which
is what it returns, except for the case of blkdev_get_by_dev() failure.
It that case lmLogOpen() return the error with the wrong sign...
