The pd->lock mutex is released on a successful return, so it should be released on an error return as well. The semantic patch that makes this change is as follows: (http://www.emn.fr/x-info/coccinelle/) // <smpl> @@ expression l; @@ mutex_lock(l); ... when != mutex_unlock(l) when any when strict ( if (...) { ... when != mutex_unlock(l) + mutex_unlock(l); return ...; } | mutex_unlock(l); ) // </smpl> Signed-off-by: Julia Lawall <julia@diku.dk> Signed-off-by: Roland Dreier <rolandd@cisco.com> |
