From 2a369153c82e0c83621b3e71d8f0c53394705bda Mon Sep 17 00:00:00 2001 From: Trond Myklebust Date: Mon, 13 Aug 2012 18:54:45 -0400 Subject: NFS: Clean up helper function nfs4_select_rw_stateid() We want to be able to pass on the information that the page was not dirtied under a lock. Instead of adding a flag parameter, do this by passing a pointer to a 'struct nfs_lock_owner' that may be NULL. Also reuse this structure in struct nfs_lock_context to carry the fl_owner_t and pid_t.
