The fix is usermode_driver.c one - once you've done kern_mount(), you must kern_unmount(); simple mntput() will end up with a leak. Several failure exits in there messed up that way... In practice you won't hit those particular failure exits without fault injection, though. -----BEGIN PGP SIGNATURE----- iHUEABYIAB0WIQQqUNBr3gm4hGXdBJlZ7Krx/gZQ6wUCYpvrWQAKCRBZ7Krx/gZQ 6z29AP9EZVSyIvnwXleehpa2mEZhsp+KAKgV/ENaKHMn7jiH0wD/bfgnhxIDNuc5 108E2R5RWEYTynW5k7nnP5PsTsMq5Qc= =b3Wc -----END PGP SIGNATURE----- Merge tag 'pull-18-rc1-work.mount' of git://git.kernel.org/pub/scm/linux/kernel/git/viro/vfs Pull mount handling updates from Al Viro: "Cleanups (and one fix) around struct mount handling.
