Hey,
After having received another round of acks on the idmapped mounts

This contains a fix for openat2() to make RESOLVE_BENEATH and
RESOLVE_IN_ROOT mutually exclusive. It doesn't make sense to specify both
at the same time. The openat2() selftests have been extended to verify
that these two flags can't be specified together.

Hi Linus,
Here are some time namespace fixes for v5.11.
/* Summary */
When time namespaces were introduced we missed to virtualize the "btime" field
in /proc/stat. This confuses tasks which are in another time namespace with a
virtualized boottime which is common in some container workloads.
