Subject: f2fs crypto: remove checking key context during lookup
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=d690358b2bf43f5cb12ce07d209d09b1decb79c3;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

f2fs crypto: remove checking key context during lookup

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.
