Subject: lxc: Distinguish pthread_mutex_unlock error messages
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=120fa8f855c5eed10852950c7b37f3878acdbfd9;p=thirdparty%2Flxc.git

lxc: Distinguish pthread_mutex_unlock error messages

The same message exists in lxclock.c and cgmanager.c, so print the
filename along with the message.

Before this patch:
lxc-destroy -n u1
pthread_mutex_unlock returned:1 Operation not permitted

After this patch:
xc-destroy -n u1
lxclock.c: pthread_mutex_unlock returned:1 Operation not permitted
