nfsd4: remove use of mutex for file_hashtable
As part of reducing the scope of the client_mutex, and in order to remove the need for mutexes from the callback code (so that callbacks can be done as asynchronous rpc calls), move manipulations of the file_hashtable under the recall_lock. Update the relevant comments while we're here. Signed-off-by: J. Bruce Fields <bfields@citi.umich.edu> Cc: Alexandros Batsakis <batsakis@netapp.com> Reviewed-by: Benny Halevy <bhalevy@panasas.com>
