From a52d726bbd928164609e6abc4dc967e819dbf09c Mon Sep 17 00:00:00 2001 From: Jeff Layton Date: Wed, 21 Mar 2012 09:52:02 -0400 Subject: nfsd: convert nfs4_client->cl_cb_flags to a generic flags field We'll need a way to flag the nfs4_client as already being recorded on stable storage so that we don't continually upcall. Currently, that's recorded in the cl_firststate field of the client struct. Using an entire u32 to store a flag is rather wasteful though. The cl_cb_flags field is only using 2 bits right now, so repurpose that to a generic flags field. Rename NFSD4_CLIENT_KILL to NFSD4_CLIENT_CB_KILL to make it evident that it's part of the callback flags. Add a mask that we can use for existing checks that look to see whether any flags are set, so that the new flags don't interfere. Convert all references to cl_firstate to the NFSD4_CLIENT_STABLE flag, and add a new NFSD4_CLIENT_RECLAIM_COMPLETE flag. Signed-off-by: Jeff Layton Signed-off-by: J.
