Message-ID: <20140719113316.GA23543@himangi-Dell> Date: Sat, 19 Jul 2014 17:03:16 +0530 From: Himangi Saraogi <himangi774@...il.com> To: Jeff Dike <jdike@...toit.com>, Richard Weinberger <richard@....at>, user-mode-linux-devel@...ts.sourceforge.net, user-mode-linux-user@...ts.sourceforge.net, linux-kernel@...r.kernel.org Cc: Julia Lawall <julia.lawall@...6.fr> Subject: [PATCH] uml: Eliminate NULL test after alloc_bootmem alloc_bootmem and related functions never return NULL. Thus a NULL test after calls to these functions is unnecessary. The following Coccinelle semantic patch was used for making the change: @@ expression E; statement S; @@ E = \(alloc_bootmem\|alloc_bootmem_low\|alloc_bootmem_pages\|alloc_bootmem_low_pages\)(...) ... when != E - if (E == NULL) S Signed-off-by: Himangi Saraogi <himangi774@...il.com> Acked-by: Julia Lawall <julia.lawall@...6.fr> --- arch/um/kernel/initrd.c | 2 -- 1 file changed, 2 deletions(-) diff --git a/arch/um/kernel/initrd.c b/arch/um/kernel/initrd.c index 55cead8..48bae81 100644 --- a/arch/um/kernel/initrd.c +++ b/arch/um/kernel/initrd.c @@ -37,8 +37,6 @@ static int __init read_initrd(void) } area = alloc_bootmem(size); - if (area == NULL) - return 0; if (load_initrd(initrd, area, size) == -1) return 0; -- 1.9.1 -- 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/
