Subject: keyctl: use printuid for printing UID/GID
X-Git-Tag: v4.14~19
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=db098f9a3d2864fa7ab637221654246223bf5b0c;p=strace

keyctl: use printuid for printing UID/GID

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, keyctl_get_persistent): Use printuid
instead of printf with "%d" conversion for printing UID/GID.
