Take a look at rw_verify_area() - it does a lot more than "trim down to 2Gb" - starting with "deal with mandatory locks". LSM checks as well... So that one is bogus, IMO. I've no problem with fallback per se, but rw_verify_area() should be unconditional here. If anything, we might add a variant that would skip the "trim down to 2Gb" and use it there, but skipping it entirely is wrong. -- 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
