Author: rmacklem Date: Sat May 14 02:28:21 2011 New Revision: 221871 URL: http://svn.freebsd.org/changeset/base/221871 Log: MFC: r221014,r221018 Modify the experimental NFS client so that it uses the same "struct nfs_args" as the regular NFS client. This is needed so that the old mount(2) syscall will work and it makes sharing of the diskless NFS root code easier. Eary in the porting exercise I introduced a new revision of nfs_args, but didn't actually need it, thanks to nmount(2). I re-introduced the NFSMNT_KERB flag, since it does essentially the same thing and the old one would not have been used because it never worked. I also added a few new NFSMNT_xxx flags to sys/nfsclient/nfs_args.h that are used by the experimental NFS client. Also fix the NFS client so that it doesn't bogusly set the f_flags argument of "struct statfs", Deleted: stable/8/sys/fs/nfsclient/nfsargs.h Modified: stable/8/sys/fs/nfs/nfsport.h stable/8/sys/fs/nfsclient/nfs_clvfsops.c stable/8/sys/nfsclient/nfsargs.h Directory Properties: stable/8/sys/ (props changed) stable/8/sys/amd64/include/xen/ (props changed) stable/8/sys/cddl/contrib/opensolaris/ (props changed) stable/8/sys/contrib/dev/acpica/ (props changed) stable/8/sys/contrib/pf/ (props changed) Modified: stable/8/sys/fs/nfs/nfsport.h ============================================================================== --- stable/8/sys/fs/nfs/nfsport.h Sat May 14 01:56:48 2011 (r221870) +++ stable/8/sys/fs/nfs/nfsport.h Sat May 14 02:28:21 2011 (r221871) @@ -372,7 +372,7 @@ struct ext_nfsstats { #include <fs/nfs/xdr_subs.h> #include <fs/nfs/nfscl.h> #include <fs/nfs/nfsclstate.h> -#include <fs/nfsclient/nfsargs.h> +#include <nfsclient/nfsargs.h> #include <fs/nfsclient/nfsmount.h> /* Modified: stable/8/sys/fs/nfsclient/nfs_clvfsops.c ============================================================================== --- stable/8/sys/fs/nfsclient/nfs_clvfsops.c Sat May 14 01:56:48 2011 (r221870) +++ stable/8/sys/fs/nfsclient/nfs_clvfsops.c Sat May 14 02:28:21 2011 (r221871) @@ -100,8 +100,9 @@ static void nfs_decode_args(struct mount struct nfs_args *argp, const char *, struct ucred *, struct thread *);
