Pull fsverity updates from Eric Biggers:

 - 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.
