Hello, I have noticed that when I build a kernel without CONFIG_USER_NS, generic/633 is failing. This is because despite it properly detects idmapped mounts are not supported, it still tries to execute some tests (such as fscaps test) and they rely on bits of user namespace support (e.g. /proc/<pid>/ns/user existing). I could hack some additional support check into the test but then I figured I'm not sure whether all the tests are OK to skip without CONFIG_USER_NS or whether there are not some more subtle dependencies... So I'm asking here :). Honza -- Jan Kara <jack@xxxxxxxx> SUSE Labs, CR
