Subject: [PATCH v2 0/2] Introduce simple pidfd to task helper

From: Christian Brauner <christian.brauner@...ntu.com>

Hey everyone,

This adds a simple helper to get rid of some code duplication introduced
with the addition of two new pidfd-based syscalls in mm. We should've
probably added the helper right away and I think I mentioned this during
in the review on one of the revisions but we probably just lost track of
it. If this looks ok to you, I'll queue this up for next.

/* v2 */
Add a note to the kernel doc what the caller is expected to clean up.
No semantical changes.

Thanks!
Christian
