[PATCH 1/8] keyctl: Use printuid for printing UID/GID

[Eugene Syromyatnikov]

UID/GID are unsigned except special -1 value (which is also special in
context of specific keyctl commands), so special printing function
should be used.

* keyctl.c (keyctl_chown_key): Use printuid instead of printf with "%d"
  conversion for printing UID/GID.
  (keyctl_get_persistent): Likewise.
