[f2fs-dev] [PATCH v2] Revert "ext4 crypto: fix to check feature status before get policy"

2019-10-30 Thread Eric Biggers
From: Douglas Anderson This reverts commit 0642ea2409f3 ("ext4 crypto: fix to check feature status before get policy"). The commit made a clear and documented ABI change that is not backward compatible. There exists userspace code [1][2] that relied on the old behavior and is now broken.
