Subject: pidns: Export free_pid_ns
X-Git-Url: http://drtracing.org/?a=commitdiff_plain;h=523a6a945f3cf5f1d337e50634687a577a732a5f;p=deliverable%2Flinux.git

pidns: Export free_pid_ns

There is a least one modular user so export free_pid_ns so modules can
capture and use the pid namespace on the very rare occasion when it
makes sense.
