H A D.gitignore01eadc8d Thu Jan 21 07:19:55 CST 2021 Christian Brauner <christian.brauner@ubuntu.com> tests: add mount_setattr() selftests

Add a range of selftests for the new mount_setattr() syscall to verify
that it works as expected. This tests that:
- no invalid flags can be specified
- changing properties of a single mount works and leaves other mounts in
the mount tree unchanged
- changing a mount tre to read-only when one of the mounts has writers
fails and leaves the whole mount tree unchanged
- changing mount properties from multiple threads works
- changing atime settings works
- changing mount propagation works
- changing the mount options of a mount tree where the individual mounts
in the tree have different mount options only changes the flags that
were requested to change
- changing mount options from another mount namespace fails
- changing mount options from another user namespace fails
- idmapped mounts

Note, the main test-suite for idmapped mounts is part of xfstests and is
pretty huge. These tests here just make sure that the syscalls bits work
correctly.
