charset="us-ascii" Content-Transfer-Encoding: 7bit Errors-To: linux-f2fs-devel-bounces@lists.sourceforge.net From: Eric Biggers Wire up the new ioctls for adding and removing fscrypt keys to/from the filesystem, and the new ioctl for retrieving v2 encryption policies. FS_IOC_REMOVE_ENCRYPTION_KEY also required making UBIFS use fscrypt_drop_inode(). For more details see Documentation/filesystems/fscrypt.rst and the fscrypt patches that added the implementation of these ioctls.
