Merge tag 'vfs-6.9.uuid' of git://git.kernel.org/pub/scm/linux/kernel/git/vfs/vfs
Pull vfs uuid updates from Christian Brauner:
"This adds two new ioctl()s for getting the filesystem uuid and
retrieving the sysfs path based on the path of a mounted filesystem.
Getting the filesystem uuid has been implemented in filesystem
specific code for a while it's now lifted as a generic ioctl"
* tag 'vfs-6.9.uuid' of git://git.kernel.org/pub/scm/linux/kernel/git/vfs/vfs:
xfs: add support for FS_IOC_GETFSSYSFSPATH
fs: add FS_IOC_GETFSSYSFSPATH
fat: Hook up sb->s_uuid
fs: FS_IOC_GETUUID
ovl: convert to super_set_uuid()
