Subject: [PATCH] Use list_first_entry in locks_wake_up_blocks
Date: Wed, 19 Sep 2007 16:44:07 +0400	[thread overview]
Message-ID: <46F11997.7030005@openvz.org> (raw)

This routine deletes all the elements from the list
with the "while (!list_empty())" loop, and we already
have a list_first_entry() macro to help it look nicer :)
