The following patch series performs a number of cleanups on the readdir
code.
It also adds support for 1MB readdir RPC calls on-the-wire, and modifies
the caching code to ensure that we cache the entire contents of that
1MB call (instead of discarding the data that doesn't fit into a single
page).

v2: Fix the handling of the NFSv3/v4 directory verifier
v3: Optimise searching when the readdir cookies are seen to be ordered

Trond Myklebust (17):
  NFS: Ensure contents of struct nfs_open_dir_context are consistent
  NFS: Clean up readdir struct nfs_cache_array
  NFS: Clean up nfs_readdir_page_filler()
  NFS: Clean up directory array handling
  NFS: Don't discard readdir results
  NFS: Remove unnecessary kmap in nfs_readdir_xdr_to_array()
  NFS: Replace kmap() with kmap_atomic() in nfs_readdir_search_array()
  NFS: Simplify struct nfs_cache_array_entry
  NFS: Support larger readdir buffers
  NFS: More readdir cleanups
  NFS: nfs_do_filldir() does not return a value
  NFS: Reduce readdir stack usage
  NFS: Cleanup to remove nfs_readdir_descriptor_t typedef
  NFS: Allow the NFS generic code to pass in a verifier to readdir
  NFS: Handle NFS4ERR_NOT_SAME and NFSERR_BADCOOKIE from readdir calls
  NFS: Improve handling of directory verifiers
  NFS: Optimisations for monotonically increasing readdir cookies
