Marko Mäkelä ba81009f63 MDEV-34863 RAM Usage Changed Significantly Between 10.11 Releases 
innodb_buffer_pool_size_auto_min: A minimum innodb_buffer_pool_size that
a Linux memory pressure event can lead to shrinking the buffer pool to.
On a memory pressure event, we will attempt to shrink
innodb_buffer_pool_size halfway between its current value and
innodb_buffer_pool_size_auto_min. If innodb_buffer_pool_size_auto_min is
specified as 0 or not specified on startup, its default value will be
adjusted to innodb_buffer_pool_size_max, that is, memory pressure events
will be disregarded by default.

buf_pool_t::garbage_collect(): For up to 15 seconds, attempt to shrink
the buffer pool in response to a memory pressure event.

Set to 0 (write and flush redo log to disk only once per second), 1 (flush to disk at each commit), 2 (write to log at commit but flush to disk only once per second) or 3 (flush to disk at prepare and at commit, slower and usually redundant). 1 and 3 guarantees that after a crash, committed transactions will not be lost and will be consistent with the binlog and other transactional engines. 2 can get inconsistent and lose transactions if there is a power failure or kernel crash but not if mysqld crashes. 0 has no guarantees in case of crash. 0 and 2 can be faster than 1 or 3.
