The quilt patch titled Subject: ufs: replace ll_rw_block() has been removed from the -mm tree. Its filename was ufs-replace-ll_rw_block.patch This patch was dropped because it was merged into the mm-stable branch of git://git.kernel.org/pub/scm/linux/kernel/git/akpm/mm ------------------------------------------------------ From: Zhang Yi <yi.zhang@xxxxxxxxxx> Subject: ufs: replace ll_rw_block() Date: Thu, 1 Sep 2022 21:35:02 +0800 ll_rw_block() is not safe for the sync read path because it cannot guarantee that submitting read IO if the buffer has been locked. We could get false positive EIO after wait_on_buffer() if the buffer has been locked by others. So stop using ll_rw_block() in ufs.
