Re: [PATCH 0/3] pidfd: add pidfd_prepare()

This adds the pidfd_prepare() helper which allows the caller to reserve
a pidfd number and allocates a new pidfd file that stashes the provided
struct pid.

This will allow us to remove places that either open code this
functionality e.g., during copy_process() or that currently call
pidfd_create() but then have to call close_fd() because there are still
failure points after pidfd_create() has been called.

Jan, thanks for the reviews.

I've picked this up now. Please note that this series is considered stable and
has thus been tagged. The reason is that the SCM_PIDFD work in the networking
depends wants to depend on this work. So they'll get a stable tag,

tree: git://git.kernel.org/pub/scm/linux/kernel/git/brauner/linux.git
branch: pidfd.file.api
tag: pidfd.file.api.v6.4
