  fscrypt: document testing with xfstests (2019-06-27 10:29:46 -0700)

----------------------------------------------------------------
fscrypt updates for v5.3

- Preparations for supporting encryption on ext4 filesystems where the
  filesystem block size is smaller than PAGE_SIZE.

- Don't allow setting encryption policies on dead directories.

- Various cleanups.

----------------------------------------------------------------
Chandan Rajendra (3):
      ext4: clear BH_Uptodate flag on decryption error
      ext4: decrypt only the needed blocks in ext4_block_write_begin()
      ext4: decrypt only the needed block in __ext4_block_zero_page_range()

Eric Biggers (14):
      fscrypt: simplify bounce page handling
      fscrypt: remove the "write" part of struct fscrypt_ctx
      fscrypt: rename fscrypt_do_page_crypto() to fscrypt_crypt_block()
      fscrypt: clean up some BUG_ON()s in block encryption/decryption
      fscrypt: introduce fscrypt_encrypt_block_inplace()
      fscrypt: support encrypting multiple filesystem blocks per page
      fscrypt: handle blocksize < PAGE_SIZE in fscrypt_zeroout_range()
      fscrypt: introduce fscrypt_decrypt_block_inplace()
      fscrypt: support decrypting multiple filesystem blocks per page
      fscrypt: decrypt only the needed blocks in __fscrypt_decrypt_bio()
      ext4: encrypt only up to last block in ext4_bio_write_page()
      fscrypt: remove unnecessary includes of ratelimit.h
      fscrypt: remove selection of CONFIG_CRYPTO_SHA256
      fscrypt: document testing with xfstests

Hongjie Fang (1):
      fscrypt: don't set policy for a dead directory
