This is a note to let you know that I've just added the patch titled random: cleanup integer types to the 4.19-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: random-cleanup-integer-types.patch and it can be found in the queue-4.19 subdirectory. If you, or anyone else, feels it should not be added to the stable tree, please let <stable@xxxxxxxxxxxxxxx> know about it. >From foo@baz Fri Jun 17 08:58:56 AM CEST 2022 From: "Jason A. Donenfeld" <Jason@xxxxxxxxx> Date: Sun, 9 Jan 2022 17:48:58 +0100 Subject: random: cleanup integer types From: "Jason A. Donenfeld" <Jason@xxxxxxxxx> commit d38bb0853589c939573ea50e9cb64f733e0e273d upstream. Rather than using the userspace type, __uXX, switch to using uXX. And rather than using variously chosen `char *` or `unsigned char *`, use `u8 *` uniformly for things that aren't strings, in the case where we are doing byte-by-byte traversal.
