--- Comment #63 from Matthew Stapleton (matthew4196@gmail.com) ---
I can't seem to trigger the problem now even with all the patches disabled and
/sys/fs/ext4/<dev>/mb_best_avail_max_trim_order set to the default of 3 so
unfortunately I won't be able to help with this problem for now.
According to perf record -ag sleep 5 at the moment most of the ext4 cpu usage
is in ext4_get_group_desc and ext4_get_group_info , both called from
ext4_mb_prefetch and some usage in ext4_mb_good_group called from
ext4_mb_find_good_group_avg_frag_lists . Both ext4_mb_prefetch and
ext4_mb_find_good_group_avg_frag_lists were called from
ext4_mb_regular_allocator. But this is all fairly low cpu usage at the moment
and it all stops shortly after the file operation is completed.
