Subject: [PATCH 0/6] Make block_read_full_page synchronous

This patchset does I/Os in larger chunks, if the blocks are adjacent.
More importantly, it returns the actual error from ->readpage for
filesystems which use block_read_full_page().  Unless fscrypt returns
an error, in which case it turns into EIO because it has to roundtrip
through bi_status.

I don't have a system with fscrypt enabled, so I'd appreciate some
testing from the fscrypt people.

Matthew Wilcox (Oracle) (6):
  block: Add blk_completion
  fs: Return error from block_read_full_page
  fs: Convert block_read_full_page to be synchronous
  fs: Hoist fscrypt decryption to bio completion handler
  fs: Turn decrypt_bh into decrypt_bio
  fs: Convert block_read_full_page to be synchronous with fscrypt
    enabled
