Status: WontFix (was: Untriaged)
Upstream commit is 91291e9998("f2fs: fix to do sanity check with block address in main area v2") Per the discussion on https://bugzilla.kernel.org/show_bug.cgi?id=200465, the fix might be incomplete as a similar bug exists with a different stacktrace. CONFIG_F2FS_FS is not set, so marking as WontFix. Will keep track of this bug in case the config flips in the future. Using configmonitor cronjob to monitor changes in kernel configs.
