Subject: Pidns: fix badly converted mqueues pid handling
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=56496c1d83dfae0c74e2f43adb45d2d95e16c0d5;p=GitHub%2FLineageOS%2Fandroid_kernel_samsung_universal7580.git

Pidns: fix badly converted mqueues pid handling

When sending the pid namespaces patches I wrongly converted the tsk->tgid into
task_pid_vnr(tsk) in mqueue-s (the git id of this patch is
b488893a390edfe027bae7a46e9af8083e740668).

The proper behavior is to get the task_tgid_vnr(tsk).

This seem to be the only mistake of that kind.
