Subject: [PATCH 02/11] perf buildid-cache: Warn --purge-all failures
From: Ravi Bangoria <ravi.bangoria@...ux.ibm.com>
Warn perf buildid-cache --purge-all failures in non verbose mode.
Ex.:
$ sudo chown root:root /home/ravi/.debug -R
$ sudo chmod 700 /home/ravi/.debug/ -R
$ ./perf buildid-cache -P
Couldn't remove some caches. Error: Permission denied.
