  fs-verity: use u64_to_user_ptr() (2020-01-14 13:28:28 -0800)

----------------------------------------------------------------

- Optimize fs-verity sequential read performance by implementing
  readahead of Merkle tree pages.  This allows the Merkle tree to be
  read in larger chunks.

- Optimize FS_IOC_ENABLE_VERITY performance in the uncached case by
  implementing readahead of data pages.

- Allocate the hash requests from a mempool in order to eliminate the
  possibility of allocation failures during I/O.

----------------------------------------------------------------
Eric Biggers (4):
      fs-verity: implement readahead for FS_IOC_ENABLE_VERITY
      fs-verity: implement readahead of Merkle tree pages
      fs-verity: use mempool for hash requests
      fs-verity: use u64_to_user_ptr()
