  ext4: sanity check the block and cluster size at mount time (2016-11-19 20:58:15 -0500)

----------------------------------------------------------------
A security fix (so a maliciously corrupted file system image won't
panic the kernel) and some fixes for CONFIG_VMAP_STACK.

----------------------------------------------------------------
Eric Biggers (2):
      fscrypto: don't use on-stack buffer for filename encryption
      fscrypto: don't use on-stack buffer for key derivation
