What should I check so this can be removed? lock kernel is the big kernel lock as in the very first lock that was added when Linux grew SMP support. If you filesystem does internal locking you most likely don't need this one at all. The only superblock method still called with the BKL in the vfs tree is remount, but it will most likely be gone before 2.6.31, too. After that you can do a quick audit if there was anything it protected against and remove it. -- To unsubscribe from this list: send the line "unsubscribe linux-fsdevel" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
