From: Julia Lawall <julia.law...@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;
