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.

Add an extra flag to hashinit telling if it should wait in malloc.
update all calls to hashinit.

(only a problem when kern.usermount == 1)

to the obvious question: don't you run this stuff before you check it
in? Sadly, the answer was no in this case. But, I'm trying to learn.
Slowly, painfully....

to be vop_generic_revoke, vop_generic_bwrite, vop_generic_islocked,
vop_generic_lock and vop_generic_unlock.
Create vop_generic_abortop and propogate change to all file systems.
Fix PR/371.
Get rid of locking in NULLFS (should be mostly unnecessary now except for
forced unmounts).

it is only used inside such regions

Strange thing still present w/ removes, the situation
seemd to be like extra VREF made somewhere, that is,
lower nfs does not remove, but rename file in '.nfs*' thing that
disapears at umap umount. this thing happend w/ nullfs too.
|
|
Types changes and so.
|
|
speaker upgraded to the current.
some changes to the VM stuff (ie kern_thread.c added and so).
|
|
|

Sync with NetBSD 960217
|
|
Still seemed to have at least one bug. Strange panic happened
when unmounting from NFS tree.
