Merge patch series "drop BUG_ON() NULL checks in namespace copy helpers"

Shaojie Sun <sunshaojie@kylinos.cn> says:

The copy_*_ns() helpers are inconsistent in how they handle a NULL
namespace pointer. copy_mnt_ns(), copy_utsname() and copy_cgroup_ns()
have a BUG_ON() on the pointer, while copy_time_ns(), copy_pid_ns(),
copy_ipcs() and copy_net_ns() don't check it at all.

The sole caller, create_new_namespaces(), always passes the
corresponding namespace pointer from the task's nsproxy, so the checks
can never trigger and the helpers dereference the pointer right away
anyway.

Drop the BUG_ON()s so that all copy_*_ns() helpers behave consistently.
