This is a note to let you know that I've just added the patch titled f2fs: set SBI_NEED_FSCK flag when inconsistent node block found to the 5.15-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: f2fs-set-sbi_need_fsck-flag-when-inconsistent-node-b.patch and it can be found in the queue-5.15 subdirectory. If you, or anyone else, feels it should not be added to the stable tree, please let <stable@xxxxxxxxxxxxxxx> know about it. commit 06215e5f1d7114ed82e2a1f7156119ecc5b5f1d3 Author: Weichao Guo <guoweichao@xxxxxxxx> Date: Sat Sep 18 20:46:36 2021 +0800 f2fs: set SBI_NEED_FSCK flag when inconsistent node block found [ Upstream commit 6663b138ded1a59e630c9e605e42aa7fde490cdc ] Inconsistent node block will cause a file fail to open or read, which could make the user process crashes or stucks. Let's mark SBI_NEED_FSCK flag to trigger a fix at next fsck time. After unlinking the corrupted file, the user process could regenerate a new one and work correctly.
