Subject: [f2fs-dev] [PATCH] f2fs: avoid inifinite loop to wait for flushing node pages at cp_error
Date: Fri, 22 May 2020 07:47:52 -0700
Message-ID: <20200522144752.216197-1-jaegeuk@kernel.org> (raw)

Shutdown test is somtime hung, since dirty node pages weren't flushed out.
Let's drop dirty pages at umount after shutdown.
