| Subject | [PATCH 15/39] bcache: drop null test before destroy functions |
| Message-ID | <q8eJB-7J8-21@gated-at.bofh.it> |
Remove unneeded NULL test.
The semantic patch that makes this change is as follows:
(http://coccinelle.lip6.fr/)
// <smpl>
@@ expression x; @@
-if (x != NULL)
\(kmem_cache_destroy\|mempool_destroy\|dma_pool_destroy\)(x);
// </smpl>
