| |
From: Julia Lawall <Julia.Lawall@lip6.fr>
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; @@ - OBD_FREE(ptr, size); + kfree(ptr); // </smpl>
