[HPDD-discuss] [PATCH 11/11] staging: lustre: ptlrpc: Use kzalloc and kfree

From: Julia Lawall <Julia.Lawall(a)lip6.fr&gt; 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/) // <smpl> @@ expression ptr,size; @@ - OBD_ALLOC(ptr,size) + ptr = kzalloc(size, GFP_NOFS) @@ expression ptr, size;
