Subject: [PATCH 0/2] nilfs2: fix kernel bug at submit_bh_wbc()

Hi Andrew,

please apply this series as a bug fix.

This resolves a kernel BUG reported by syzbot.  Since there are two
flaws involved, I've made each one a separate patch.

The first patch alone resolves the syzbot-reported bug, but I think
both fixes should be sent to stable, so I've tagged them as such.

This series does not conflict with the currently queued conversion
to kmap_local series, etc and can be applied independently.

Thanks,
Ryusuke Konishi
