Subject: [PATCH 18/18] f2fs crypto: remove checking key context during lookup
Date: Fri,  8 May 2015 21:20:53 -0700	[thread overview]
Message-ID: <1431145253-2019-18-git-send-email-jaegeuk@kernel.org> (raw)
In-Reply-To: <1431145253-2019-1-git-send-email-jaegeuk@kernel.org>

No matter what the key is valid or not, readdir shows the dir entries correctly.
So, lookup should not failed.
But, we expect further accesses should be denied from open, rename, link, and so
on.
