[PATCH 0/7] pidfd_getfd: fix decoder

[Ákos Uzonyi]

From: Uzonyi Ákos <uzonyi.akos at gmail.com>

These patches fix pidfd_getfd decoder, which incorrectly assumed its
first argument being a pid, but actually that is a pidfd.

First, some functions are added to util.c, which makes the decoding possible.

Ákos Uzonyi (7):
  pathtrace.c: add getfdpath_pid
  util.c: add printfd_pid
  Rename print_pid_fd -> printfd_pid_tracee_ns
  util.c: add pidfd_get_pid
  util.c: pidfd_get_pid: check if pidfd refers to a non visible process
  pidfd_getfd: fix decoder
  tests/pidfd_getfd.c: test decoding of targetfd
