Subject[PATCH] f2fs: fix flushing node pages when checkpoint is disabled
Date
This patch fixes skipping node page writes when checkpoint is disabled.
In this period, we can't rely on checkpoint to flush node pages.

Fixes: fd8c8caf7e7c ("f2fs: let checkpoint flush dnode page of regular")
Fixes: 4354994f097d ("f2fs: checkpoint disabling")
