From 7b81779d0dd62316d4f92fab96eeba9ddfa3aaa6 Mon Sep 17 00:00:00 2001 From: Julia Lawall Date: Fri, 1 May 2015 17:51:17 +0200 Subject: [PATCH] staging: lustre: mdc: Use kzalloc and kfree Replace OBD_ALLOC, OBD_ALLOC_WAIT, OBD_ALLOC_PTR, and OBD_ALLOC_PTR_WAIT by kalloc/kcalloc, and OBD_FREE and OBD_FREE_PTR by kfree. A simplified version of the semantic patch that makes these changes is as follows: (http://coccinelle.lip6.fr/) // @@ expression ptr,size; @@ - OBD_ALLOC(ptr,size) + ptr = kzalloc(size, GFP_NOFS) @@ expression ptr, size;
