This series adds a new syscall quotactl_path() which replaces the path to the block device with a mountpath, but otherwise behaves like original quotactl. This is done to add quota support to UBIFS. UBIFS quota support has been posted several times with different approaches to put the mountpath into the existing quotactl() syscall until it has been suggested to make it a new syscall instead, so here it is. I'm not posting the full UBIFS quota series here as it remains unchanged and I'd like to get feedback to the new syscall first.
