If the flock owner process is dead and its pid has been already freed,
pid translation won't work, but we still want to show flock owner pid
number when expecting /proc/$PID/fdinfo/$FD in init pidns.
Reproducer:
process A process A1 process A2
fork()--------->
exit() open()
flock()
fork()--------->
exit() sleep()
Before the patch:
================
(root@vz7)/: cat /proc/${PID_A2}/fdinfo/3
pos: 4
flags: 02100002
mnt_id: 257
lock: (root@vz7)/:
After the patch:
===============
(root@vz7)/:cat /proc/${PID_A2}/fdinfo/3
pos: 4
flags: 02100002
mnt_id: 295
lock: 1: FLOCK ADVISORY WRITE ${PID_A1} b6:f8a61:529946 0 EOF

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
See Documentation/00-INDEX for a list of what is contained in each file.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
