From ef921adb8d7e32b181c8c0cee764ec21824f98e1 Mon Sep 17 00:00:00 2001 From: millert Date: Mon, 31 May 1999 17:34:39 +0000 Subject: New struct statfs with mount options. NOTE: this replaces statfs(2), fstatfs(2), and getfsstat(2) so you will need to build a new kernel before doing a "make build" or you will get "unimplemented syscall" errors. The new struct statfs has the following featuires: o Has a u_int32_t flags field--now softdep can have a real flag. o Uses u_int32_t instead of longs (nicer on the alpha). Note: the man page used to lie about setting invalid/unused fields to -1. SunOS does that but our code never has. o Gets rid of f_type completely. It hasn't been used since NetBSD 0.9 and having it there but always 0 is confusing. It is conceivable that this may cause some old code to not compile but that is better than silently breaking. o Adds a mount_info union that contains the FSTYPE_args struct. This means that "mount" can now tell you all the options a filesystem was mounted with. This is especially nice for NFS. Other changes: o The linux statfs emulation didn't convert between BSD fs names and linux f_type numbers. Now it does, since the BSD f_type number is useless to linux apps (and has been removed anyway) o FreeBSD's struct statfs is different from our (both old and new) and thus needs conversion. Previously, the OpenBSD syscalls were used without any real translation. o mount(8) will now show extra info when invoked with no arguments. However, to see *everything* you need to use the -v (verbose) flag. --- sys/kern/vfs_subr.c | 3 +-- 1 file changed, 1 insertion(+), 2 deletions(-) (limited to 'sys/kern/vfs_subr.c') diff --git a/sys/kern/vfs_subr.c b/sys/kern/vfs_subr.c index 4df9a385a12..a44fa140711 100644 --- a/sys/kern/vfs_subr.c +++ b/sys/kern/vfs_subr.c @@ -1,4 +1,4 @@ -/* $OpenBSD: vfs_subr.c,v 1.38 1999/05/06 15:59:40 mickey Exp $ */ +/* $OpenBSD: vfs_subr.c,v 1.39 1999/05/31 17:34:48 millert Exp $ */ /* $NetBSD: vfs_subr.c,v 1.53 1996/04/22 01:39:13 christos Exp $ */ /* @@ -222,7 +222,6 @@ vfs_rootmountalloc(fstypename, devname, mpp) mp->mnt_flag = MNT_RDONLY; mp->mnt_vnodecovered = NULLVP; vfsp->vfc_refcount++; - mp->mnt_stat.f_type = vfsp->vfc_typenum; mp->mnt_flag |= vfsp->vfc_flags & MNT_VISFLAGMASK; strncpy(mp->mnt_stat.f_fstypename, vfsp->vfc_name, MFSNAMELEN); mp->mnt_stat.f_mntonname[0] = '/'; -- cgit v1.2.3-59-g8ed1b
