Subject: Use list_first_entry in locks_wake_up_blocks
X-Git-Tag: v2.6.24-rc1~1274^2~12
X-Git-Url: https://err.no/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=f0c1cd0eaf0b127356c2c09e40305453bc361b0f;p=linux-2.6

Use list_first_entry in locks_wake_up_blocks

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 :)
