Date: Sun, 12 Apr 2015 23:19:48 +0200 From: Julia Lawall <Julia.Lawall@...6.fr> To: linux-kernel@...r.kernel.org Cc: kernel-janitors@...r.kernel.org, devel@...verdev.osuosl.org, HPDD-discuss@...ts.01.org, Greg Kroah-Hartman <gregkh@...uxfoundation.org>, Andreas Dilger <andreas.dilger@...el.com>, Oleg Drokin <oleg.drokin@...el.com> Subject: [PATCH] drop uses of some OBD alloc and free functions Replace OBD_ALLOC, OBD_ALLOC_WAIT, OBD_ALLOC_PTR, and OBD_ALLOC_PTR_WAIT by kzalloc or calloc, as appropriate. Replace OBD_FREE and OBD_FREE_PTR by kfree. The complete semantic patch that makes these changes is as follows: (http://coccinelle.lip6.fr/) // <smpl> @@ expression ptr,e1,e2; @@ - OBD_ALLOC(ptr,sizeof e1 * e2) + ptr = kcalloc(e2, sizeof e1, GFP_NOFS) @@ expression ptr,e1,e2; @@ - OBD_ALLOC_WAIT(ptr,sizeof e1 * e2) + ptr = kcalloc(sizeof e1, e2, GFP_KERNEL) @@ expression ptr,e1,e2; @@ - OBD_ALLOC(ptr,e2 * sizeof e1) + ptr = kcalloc(e2, sizeof e1, GFP_NOFS) @@ expression ptr,e1,e2; @@ - OBD_ALLOC_WAIT(ptr,e2 * sizeof e1) + ptr = kcalloc(e2, sizeof e1, GFP_KERNEL) @@ expression ptr,e2; type t; @@ - OBD_ALLOC(ptr,sizeof (t) * e2) + ptr = kcalloc(e2, sizeof (t), GFP_NOFS) @@ expression ptr,e2; type t; @@ - OBD_ALLOC_WAIT(ptr,sizeof (t) * e2) + ptr = kcalloc(e2, sizeof (t), GFP_KERNEL) @@ expression ptr,e2; type t; @@ - OBD_ALLOC(ptr,e2 * sizeof (t)) + ptr = kcalloc(e2, sizeof (t), GFP_NOFS) @@ expression ptr,e2; type t; @@ - OBD_ALLOC_WAIT(ptr,e2 * sizeof (t)) + ptr = kcalloc(e2, sizeof (t), GFP_KERNEL) @@ expression ptr,e1,e2; @@ - OBD_ALLOC(ptr,e1 * e2) + ptr = kcalloc(e1, e2, GFP_NOFS) @@ expression ptr,e1,e2; @@ - OBD_ALLOC_WAIT(ptr,e1 * e2) + ptr = kcalloc(e1, e2, GFP_KERNEL) // ----------------------------------------------------------------------- @@ expression ptr,size; @@ - OBD_ALLOC(ptr,size) + ptr = kzalloc(size, GFP_NOFS) @@ expression ptr,size; @@ - OBD_ALLOC_WAIT(ptr,size) + ptr = kzalloc(size, GFP_KERNEL) @@ expression ptr; @@ - OBD_ALLOC_PTR(ptr) + ptr = kzalloc(sizeof(*ptr), GFP_NOFS) @@ expression ptr; @@ - OBD_ALLOC_PTR_WAIT(ptr) + ptr = kzalloc(sizeof(*ptr), GFP_KERNEL) // ---------------------------------------------------------------------- @@ expression ptr, size; @@ - OBD_FREE(ptr, size); + kfree(ptr); @@ expression ptr; @@ - OBD_FREE_PTR(ptr); + kfree(ptr); // </smpl> -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@...r.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
