mainline inclusion from mainline-master commit 11364d61314eb97b12d6b6facb1ededada52fcc1 category: feature bugzilla: https://gitee.com/openeuler/kernel/issues/I5MK7S CVE: NA
Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?i...
----------------------------------------------------------------------
Use bitmap_zalloc()/bitmap_free() instead of hand-writing them. It is less verbose and it improves the semantic.
While at it, add an explicit include <linux/bitmap.h>.
