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