From: Eric Biggers <ebiggers@xxxxxxxxxx> This series removes checks for a regular file's encryption key that occur after we've already opened the file. We're guaranteed to already have the key in such places, since we require it in ->open(). open() fails with ENOKEY otherwise, and a file descriptor is never made available. This pertains to regular files only. (Directories can be opened with or without their key.)
