This is a note to let you know that I've just added the patch titled libceph: rename read_sparse_msg_*() to read_partial_sparse_msg_*() to the 6.6-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: libceph-rename-read_sparse_msg_-to-read_partial_spar.patch and it can be found in the queue-6.6 subdirectory. If you, or anyone else, feels it should not be added to the stable tree, please let <stable@xxxxxxxxxxxxxxx> know about it. commit ac25c33671479a4f4557865ef4371824ca845da2 Author: Xiubo Li <xiubli@xxxxxxxxxx> Date: Thu Dec 14 09:21:15 2023 +0800 libceph: rename read_sparse_msg_*() to read_partial_sparse_msg_*() [ Upstream commit ee97302fbc0c98a25732d736fc73aaf4d62c4128 ] These functions are supposed to behave like other read_partial_*() handlers: the contract with messenger v1 is that the handler bails if the area of the message it's responsible for is already processed. This comes up when handling short reads from the socket.
