3bea22184e Get the declaration of `struct dirent' from <sys/dirent.h>, not from
<sys/dir.h>.

Removed unused #include.

Fixed type and order of struct members in pseudo-declaration of `struct
vop_readdir_args'.

3ac4d1ef0c Don't #include <sys/fcntl.h> in <sys/file.h> if KERNEL is defined.
Fixed everything that depended on getting fcntl.h stuff from the wrong
place.  Most things don't depend on file.h stuff at all.

cc9d89901f Restore the lost MNT_LOCAL flag twiddle. Lite2 has a different mechanism
of setting it (compiled into vfs_conf.c), but we have a dynamic system
in place.  This could probably be better done via a runtime configure
flag in the VFS_SET() VFS declaration, perhaps VFCF_LOCAL, and have the
VFS code propagate this down into MNT_LOCAL at mount time.  The other FS's
would need to be updated, havinf UFS and MSDOSFS filesystems without
MNT_LOCAL breaks a few things..  the man page rebuild scans for local
filesystems and currently fails, I suspect that other tools like find
and tar with their "local filesystem only" modes might be affected.

8092a8e143 Make this compile without warnings after the Lite2 merge:
- *fs_init routines now take a "struct vfsconf * vfsp" pointer
  as an argument.
- Use the correct type for cookies.
- Update function prototypes.

996c772f58 This is the kernel Lite/2 commit. There are some requisite userland
changes, so don't expect to be able to run the kernel as-is (very well)
without the appropriate Lite/2 userland changes.

The system boots and can mount UFS filesystems.

Untested: ext2fs, msdosfs, NFS
Known problems: Incorrect Berkeley ID strings in some files.
		Mount_std mounts will not work until the getfsent
		library routine is changed.

1130b656e5 Make the long-awaited change from $Id$ to $FreeBSD$
This will make a number of things easier in the future, as well as (finally!)
avoiding the Id-smashing problem which has plagued developers for so long.

Boy, I'm glad we're not using sup anymore.  This update would have been
insane otherwise.

fdd71f982f Don't synchronously update the directory entry at the end of every
successful write.  Only do it for the IO_SYNC case (like ufs).  On
one of my systems, this speeds up `iozone 24 512' from 32K/sec
(1/128 as fast as ufs) to 2.8MB/sec (7/10 as fast as ufs).

39b1a97c77 MSDOS FS used to allocate a buffer before extending the VM object. In
certain error conditions, it is possible for pages to be left allocated
in the object beyond it's end.  It is generally bad practice to allocate
pages beyond the end of an object.

process won't possibly block before filling in the fsnode pointer (v_data)
which might be dereferenced during a sync since the vnode is put on the

f57e65478d Introduced a type `vop_t' for vnode operation functions and used
it 1138 times (:-() in casts and a few more times in declarations.
This change is null for the i386.

The type has to be `typedef int vop_t(void *)' and not `typedef
int vop_t()' because `gcc -Wstrict-prototypes' warns about the
latter.  Since vnode op functions are called with args of different
(struct pointer) types, neither of these function types is any use
for type checking of the arg, so it would be preferable not to use
the complete function type, especially since using the complete
type requires adding 1138 casts to avoid compiler warnings and
another 40+ casts to reverse the function pointer conversions before
calling the functions.

msdosfs_lookup() did no validation to see if the caller was validated
to delete/rename/create files.  msdosfs_setattr() did no validation
to see if the caller was allowed to change the file permissions (turn
on/off the write bit) or update the file modification time (utimes).

The routines were fixed to validate the calls just like ufs does.

Fix PR 303: msdosfs: moving a file into another directory causes panic.

" ... the code that does the rename already has the denode
locked when msdosfs_hashins() gets called, resulting in the panic
when the routine attempts to lock the denode again.
...
The attached patch changes the msdosfs_hashins() routine to not lock the
denode.  The caller is now resposible for obtaining the lock instead
of having msdosfs_hashins() do it for them."
