[PATCH v10 6/6] xfs/530: quotas on idmapped mounts

[Christian Brauner <brauner@kernel.org>]

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

This is basically a re-implementation of xfs/050 but each file creation
call is done through an idmapped mount which verifies that the semantics
are identical even when the mount is idmapped.
