Subject: [PATCH v5 0/6] capabilities: Introduce CAP_CHECKPOINT_RESTORE

This is v5 of the 'Introduce CAP_CHECKPOINT_RESTORE' patchset. The
changes to v4 are:

 * split into more patches to have the introduction of
   CAP_CHECKPOINT_RESTORE and the actual usage in different
   patches
 * reduce the /proc/self/exe patch to only be about
   CAP_CHECKPOINT_RESTORE

Adrian Reber (5):
  capabilities: Introduce CAP_CHECKPOINT_RESTORE
  pid: use checkpoint_restore_ns_capable() for set_tid
  pid_namespace: use checkpoint_restore_ns_capable() for ns_last_pid
  proc: allow access in init userns for map_files with CAP_CHECKPOINT_RESTORE
  selftests: add clone3() CAP_CHECKPOINT_RESTORE test

Nicolas Viennot (1):
  prctl: Allow checkpoint/restore capable processes to change exe link
