From: Christian Brauner <christian.brauner@xxxxxxxxxx> Hey, This introduces two new idmapped mount tests. The first test extends the v3 fscaps tests for idmapped mounts. The second test verified that idmapped mounts behave correctly when nested user namespaces are used. In essence it creates a fairly complex nested user namespace hierarchy and then tests whether file ownership changes are correctly reflected in all idmapped mounts as seen from all those user namespaces. In addition this fixes a couple of minor things and shares more code between the mount-idmapped and idmapped-mounts binaries. Thanks!
