Zdenek Kabelac reported that his syslog was flooded with many messages:
Purging GPU memory, 0 pages freed, 0 pages still pinned, 2029 pages left available.
It happened when he was testing the VDO device mapper module (which
requires a lot of kernel memory).
This commit changes the message to be ratelimited, so that it doesn't spam
the syslog.
