Date: Sat, 19 Jul 2014 17:01:57 +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_low_pages 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/physmem.c | 2 -- 1 file changed, 2 deletions(-) diff --git a/arch/um/kernel/physmem.c b/arch/um/kernel/physmem.c index 30fdd5d..fb041cf 100644 --- a/arch/um/kernel/physmem.c +++ b/arch/um/kernel/physmem.c @@ -43,8 +43,6 @@ int __init init_maps(unsigned long physmem, unsigned long iomem, total_len = phys_len + iomem_len + highmem_len; map = alloc_bootmem_low_pages(total_len); - if (map == NULL) - return -ENOMEM; for (i = 0; i < total_pages; i++) { p = &map[i]; -- 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/
