Linus Torvalds 764822972d NFSD 6.2 Release Notes
This release introduces support for the CB_RECALL_ANY operation.
 NFSD can send this operation to request that clients return any
 delegations they choose. The server uses this operation to handle
 low memory scenarios or indicate to a client when that client has
 reached the maximum number of delegations the server supports.
 
 The NFSv4.2 READ_PLUS operation has been simplified temporarily
 whilst support for sparse files in local filesystems and the VFS is
 improved.
 
 Two major data structure fixes appear in this release:
 
 * The nfs4_file hash table is replaced with a resizable hash table
   to reduce the latency of NFSv4 OPEN operations.
 
 * Reference counting in the NFSD filecache has been hardened against
   races.
 
 In furtherance of removing support for NFSv2 in a subsequent kernel
 release, a new Kconfig option enables server-side support for NFSv2
 to be left out of a kernel build.
 
 MAINTAINERS has been updated to indicate that changes to fs/exportfs
 should go through the NFSD tree.
