This is a note to let you know that I've just added the patch titled lib/crc32.c: fix trivial typo in preprocessor condition to the 4.9-stable tree which can be found at: http://www.kernel.org/git/?p=linux/kernel/git/stable/stable-queue.git;a=summary The filename of the patch is: lib-crc32.c-fix-trivial-typo-in-preprocessor-conditi.patch and it can be found in the queue-4.9 subdirectory. If you, or anyone else, feels it should not be added to the stable tree, please let <stable@xxxxxxxxxxxxxxx> know about it. commit bc783208896ff1d7156ee9741a62a22d901bd9c6 Author: Tobias Jordan <kernel@xxxxxxx> Date: Thu Oct 15 20:11:38 2020 -0700 lib/crc32.c: fix trivial typo in preprocessor condition [ Upstream commit 904542dc56524f921a6bab0639ff6249c01e775f ] Whether crc32_be needs a lookup table is chosen based on CRC_LE_BITS. Obviously, the _be function should be governed by the _BE_ define. This probably never pops up as it's hard to come up with a configuration where CRC_BE_BITS isn't the same as CRC_LE_BITS and as nobody is using bitwise CRC anyway.
