[PATCH v2 0/6] Extend idmapped mount testsuite

[Christian Brauner <brauner@kernel.org>]

From: Christian Brauner <christian.brauner@ubuntu.com>

Hey,

This adds two new tests:
- a regression test for vfs capabilities
- a new test with nested idmapping layouts

In addition, I've added a new test for btrfs which is on-track to
support idmapped mounts in v5.15. I leave it to Eryu whether he wants to
merge the btrfs test already or not. I think there's no harm in doing so
but I'm also happy to wait.

Thanks!
Christian
