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
