4585e3ac5a - Change all filesystems and vfs_cache to relock the dvp once the child is
locked in the ISDOTDOT case.  Se vfs_lookup.c r1.79 for details.

27ad03cb5d - We no longer have to bother with PDIRUNLOCK, lookup() handles it for us.
- In the ISDOTDOT case we have to unlock the dvp before locking the child,
   if this fails we must relock dvp before returning an error.  This was
   missing before.

d9b2d9f7a2 - Update vfs_root implementations to match the new prototype. None of
these filesystems will support shared locks until they are explicitly
   modified to do so.  Careful review must be done to ensure that this
   is safe for each individual filesystem.

625d4bc03a Create a vp->v_object in VFS_FHTOVP() if we want to be exportable
with NFS.

We are moving responsibility for creating the vnode_pager object into
the filesystems which own the vnode, and this is one of the places
we have to cover.

We call vnode_create_vobject() directly because we own the vnode.

If we can get the size easily, pass it as an argument to save the
call to VOP_GETATTR() in vnode_create_vobject()

935ab476fa ufs vfs_mountedon(), rely on vfs_mount.c calling VFS_STATFS() 2004-12-06 20:03:58 +00:00
Poul-Henning Kamp
743312367a VFS_STATFS(mp, ...) is mostly called with &mp->mnt_stat, but a few cases
doesn't.  Most of the implementations have grown weeds for this so they
copy some fields from mnt_stat if the passed argument isn't that.

Fix this the cleaner way:  Always call the implementation on mnt_stat
and copy that in toto to the VFS_STATFS argument if different.

aec0fb7b40 Back when VOP_* was introduced, we did not have new-style struct
initializations but we did have lofty goals and big ideals.

Adjust to more contemporary circumstances and gain type checking.

	Replace the entire vop_t frobbing thing with properly typed
	structures.  The only casualty is that we can not add a new
	VOP_ method with a loadable module.  History has not given
	us reason to belive this would ever be feasible in the the
	first place.

	Eliminate in toto VOCALL(), vop_t, VNODEOP_SET() etc.

	Give coda correct prototypes and function definitions for
	all vop_()s.

	Generate a bit more data from the vnode_if.src file:  a
	struct vop_vector and protype typedefs for all vop methods.

	Add a new vop_bypass() and make vop_default be a pointer
	to another struct vop_vector.

	Remove a lot of vfs_init since vop_vector is ready to use
	from the compiler.

	Cast various vop_mumble() to void * with uppercase name,
	for instance VOP_PANIC, VOP_NULL etc.

	Implement VCALL() by making vdesc_offset the offsetof() the
	relevant function pointer in vop_vector.  This is disgusting
	but since the code is generated by a script comparatively
	safe.  The alternative for nullfs etc. would be much worse.

	Fix up all vnode method vectors to remove casts so they
	become typesafe.  (The bulk of this is generated by scripts)

9c83534dd8 Make VOP_BMAP return a struct bufobj for the underlying storage device
instead of a vnode for it.

The vnode_pager does not and should not have any interest in what
the filesystem uses for backend.

(vfs_cluster doesn't use the backing store argument.)

5e8c582ac2 Put a version element in the VFS filesystem configuration structure
and refuse initializing filesystems with a wrong version.  This will
aid maintenance activites on the 5-stable branch.

s/vfs_mount/vfs_omount/

s/vfs_nmount/vfs_mount/

Name our filesystems mount function consistently.

Eliminate the namiedata argument to both vfs_mount and vfs_omount.
It was originally there to save stack space.  A few places abused
it to get hold of some credentials to pass around.  Effectively
it is unused.

Reorganize the root filesystem selection code.

f257b7a54b Make VFS_ROOT() and vflush() take a thread argument.
This is to allow filesystems to decide based on the passed thread
which vnode to return.
Several filesystems used curthread, they now use the passed thread.

8b149b5131 Consistently use the BSD u_int and u_short instead of the SYSV uint and

this change just makes them self-consistent.

a8d43c90af Add a "int fd" argument to VOP_OPEN() which in the future will
contain the filedescriptor number on opens from userland.

The index is used rather than a "struct file *" since it conveys a bit
more information, which may be useful to in particular fdescfs and /dev/fd/*

For now pass -1 all over the place.
