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 <[email protected]> Acked-by: Julia Lawall <[email protected]> --- 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 [email protected] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
