[PATCH 0/7] mount_setattr fixes

[Christian Brauner <brauner@kernel.org>]

Hey,

This contains a couple of minor fixes for the mount_setattr() code I
didn't get around to sending so far. Apart from making the control flow
a little easier to follow there's a fix for a long-standing braino in
one of the idmapped mount kernel selftests. The kernel selftests are
separate from the large fstests suite and are only concerned with
testing the syscall itself whereas the fstests test all related vfs and
filesystem specific functionality for idmapped mounts. I would also like
to add a maintenance entry for idmapped mounts for the few files and
documentation that I've written.
I'll be gone for ~10 days starting next week but I'll try to check-in
regularly.

Thanks!
Christian
