H A D | qcow2-cache.c | 279621c0 Tue Aug 04 12:14:40 GMT 2015 Alberto Garcia <berto@igalia.com> qcow2: add option to clean unused cache entries after some time
This adds a new 'cache-clean-interval' option that cleans all qcow2 cache entries that haven't been used in a certain interval, given in seconds.
This allows setting a large L2 cache size so it can handle scenarios with lots of I/O and at the same time use little memory during periods of inactivity.
This feature currently relies on MADV_DONTNEED to free that memory, so it is not useful in systems that don't follow that behavior.
