Subject: [PATCH] f2fs: let's keep writing IOs on SBI_NEED_FSCK
Git-commit: 1ffc8f5f7751f91fe6af527d426a723231b741a6
Patch-mainline: v5.15-rc1
References: stable-5.14.6

commit 1ffc8f5f7751f91fe6af527d426a723231b741a6 upstream.

SBI_NEED_FSCK is an indicator that fsck.f2fs needs to be triggered, so it
is not fully critical to stop any IO writes. So, let's allow to write data
instead of reporting EIO forever given SBI_NEED_FSCK, but do keep OPU.
