I have discussed with Jaegeuk about this in below thread, https://lore.kernel.org/linux-f2fs-devel/20190219081529.5106-1-yuch...@huawei.com/T/#md5d6dcf60052201994e6df4a915a07a04869d427 IMO, we need a per data type global list to cache all bios to enhance its scalability, as single bio cache may suffer performance regression due to race of multiple threads, I've sent a patch [1] for that previously. For any thoughts, we can discuss in above thread.
