Merge branch 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/ebiederm/user-namespace
Pull mqueuefs revert from Eric Biederman:
"This fixes a regression that came in the merge window for v4.16.
The problem is that the permissions for mounting and using the
mqueuefs filesystem are broken. The necessary permission check is
missing letting people who should not be able to mount mqueuefs mount
mqueuefs. The field sb->s_user_ns is set incorrectly not allowing the
mounter of mqueuefs to remount and otherwise have proper control over
the filesystem.
Al Viro and I see the path to the necessary fixes differently and I am
not even certain at this point he actually sees all of the necessary
fixes. Given a couple weeks we can probably work something out but I
don't see the review being resolved in time for the final v4.16. I
don't want v4.16 shipping with a nasty regression. So unfortunately I
am sending a revert"
