----------------------------------------------------------------
NFS client updates for Linux 3.8
Features include:
- Full audit of BUG_ON asserts in the NFS, SUNRPC and lockd client code
Remove altogether where possible, and replace with WARN_ON_ONCE and
appropriate error returns where not.
- NFSv4.1 client adds session dynamic slot table management. There is
matching server side code that has been submitted to Bruce for
consideration. Together, this code allows the server to dynamically
manage the amount of memory it allocates to the duplicate request
cache for each client. It will constantly resize those caches to
reserve more memory for clients that are hot while shrinking caches
for those that are quiescent.
In addition, there are assorted bugfixes for the generic NFS write code,
fixes to deal with the drop_nlink() warnings, and yet another fix for
NFSv4 getacl.
