Lock contention was one of the reasons why the BKL went away back in 2.6.39: https://www.linux.com/learn/tutorials/447301:whats-new-in-linux-2639-ding-dong-the-big-kernel-lock-is-dead Use a kernel that's less than 2 years old and you won't have that problem. And if you're stuck with a kernel that's older than that, you can still fix your locking to not use the BLK.
