patches to replace per-filesystem encryption config options with a
single config option that affects all filesystems making use of
fscrypt code.

ext4: use IS_ENCRYPTED() to check encryption status
f2fs: use IS_ENCRYPTED() to check encryption status
fscrypt: remove filesyste
From: Chandan Rajendra
This commit removes the f2fs specific f2fs_encrypted_inode() and makes
use of the generic IS_ENCRYPTED() macro to check for the encryption
status of an inode.

For subpage-sized blocks, the initial logical block number mapped by a
page can be different from page->index. Hence this commit adds code to
compute the first logical block mapped by the page and also the page
range to be encrypted.

For block size < page size, apart from handling bios, post read
processing needs to handle buffer heads. Hence this commit removes the
term "bio" from the identifiers associated with post read processing.

With subpage sized blocks, ext4_block_write_begin() can have up to two
blocks to decrypt. Hence this commit invokes fscrypt_decrypt_page() for
each of those blocks.

On an error return from fscrypt_decrypt_page(), ext4_block_write_begin()
can return with the page's buffer_head marked with BH_Uptodate
flag. This commit clears the BH_Uptodate flag in such cases.

2. Verity changes needs to be added for F2FS and I will add them in the
next patchset based on the review comments obtained for the current
patchset.
