2000-02-07update to use new checkexp vfs operationassar
1999-05-31New struct statfs with mount options. NOTE: this replaces statfs(2),Todd C. Miller
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.
