Hi all, This patch aims to hoist the ext4 get/set ioctls to the VFS so we have a common interface for tools such as coreutils. The second patch adds support for FS_IOC_GETFSUUID in xfs (with FS_IOC_SETFSUUID planned for future patches). In addition, the new xfs_spaceman fsuuid command uses this ioctl to retrieve the UUID of a mounted filesystem. Comments and feedback appreciated!
