Documentation/vm/page-types.c: auto debugfs mount for hwpoison operation
page-types.c doesn't supply a way to specify the debugfs path and the original debugfs path is not usual on most machines. This patch supplies a way to auto mount debugfs if needed. This patch is heavily inspired by tools/perf/utils/debugfs.c [akpm@linux-foundation.org: make functions static] [akpm@linux-foundation.org: fix debugfs_mount() signature] Signed-off-by: Chen Gong <gong.chen@linux.intel.com> Reviewed-by: KOSAKI Motohiro <kosaki.motohiro@jp.fujitsu.com> Reviewed-by: Wu Fengguang <fengguang.wu@intel.com> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
