[PATCH 0/4] fscrypt: remove checks for encryption key after file open

[Eric Biggers]

From: Eric Biggers <ebiggers at google.com>

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.)

Eric Biggers (4):
  ext4: don't bother checking for encryption key in ->mmap()
  f2fs: don't bother checking for encryption key in ->mmap()
  ubifs: don't bother checking for encryption key in ->mmap()
  f2fs: don't bother checking for encryption key in ->write_iter()
