How about enhancing the "*thread_pool=/number" mount option instead? thread_pool=n enable threadpool/**/for compression and checksum, MAY improve bandwidth/* */thread_pool=0 disable threadpool for compression and checksum, MIGHT reduce latency thread_pool=-1 or not provided automatically managed (current behaviour and default choice) This should allow user to tradeoff between latency and bandwidth, furthermore, you do not need to assume that btrfs may use crc32c algorithm only forever. /* -- To unsubscribe from this list: send the line "unsubscribe linux-btrfs" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
