CVS commit: src/sys/nfs

["Christos Zoulas" <christos%netbsd.org@localhost>]

Module Name:    src
Committed By:   christos
Date:           Wed Sep 18 16:33:14 UTC 2013

Modified Files:
        src/sys/nfs: nfs_subs.c

Log Message:
Use reference counting to keep track of construction and destruction of the
structures used by both the nfs server and client code. Tested by pgoyette@

1. mount remote fs via nfs (my /home directory), which autoloads nfs module
2. manually modload nfsserver
3. wait a bit
4. manually modunload nfsserver
5. wait a couple minutes
6. verify that client access still works (/bin/ls ~paul home dir)
7. manually modload nfsserver again
8. start an nfsd process
9. wait a bit
10. kill nfsd process
11. wait
12. manually modunload nfsserver again
13. verify continued client access

XXX: Note that nfs_vfs_init() calls nfs_init(), but nfs_vfs_done() does not
     call nfs_fini(). Also note that the destruction order is wrong in it,
     but probably does not matter. "someone" (!= me) should fix it :-) and
     run the above tests.
