coccinelle: also catch kzfree() issues

2016-06-21T09:43:32+00:00

Since commit 3ef0e5ba4673 ('slab: introduce kzfree()'), kfree() is no more the only function to be considered: kzfree() should be recognized too. In particular, kzfree() must not be called on memory allocated through devm_*() functions. Cc: Johannes Weiner Acked-by: Julia Lawall Signed-off-by: Yann Droneaud Signed-off-by: Michal Marek
