Subject: [PATCH 5.10 103/121] f2fs: set SBI_NEED_FSCK flag when inconsistent node block found
From: Weichao Guo <guoweichao@...o.com>
[ 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.
