Fix is to only plug on prep deferral if the device queue is empty
(otherwise we can rely on returning I/O to restart the queue)

It looks like the merge of Doug and Christoph's code dropped two calls
(unless the exit devfs_unregister was supposed to be removed).

Here's a patch for the addition of scsi_init_procfs, devfs_mk_dir and
bus_unregister calls, and a small reordering so calls in exit_scsi
match the reverse of those in init_scsi.

The scsi_debug version in lk 2.5.48 is the second last one
I sent to this list. So this patch includes the changes from
the last one I sent:
   - fix "in use" counting [hch]
   - clean up bios_param() code
It also merges a sysfs re-organisation from Mike Anderson.

On returning I/O, need to unplug the queue before we call the queue_fn. 
This fixes a problem in 2.5.48 where the aic7xxx driver hangs under e2fsck.

Some of that stuff might have been right for 2.4, but..

(and btw, scsi_lib is pretty misleading, what about reusing scsi_queue.c?)

Currently allocation and freeing of struct scsi_device is a mess.
We have two nice functions in scsi_scan.c (scsi_allocate_sdev/
scsi_free_sdev) that are the right interfaces to deal with it, so I moved
them to scsi and made them non-static.  I've changed all functions
allocation freeing them to use it.

*grr* - silly typedefs..

sending routines don't set it up.

from "write()" is an error condition, and hang retrying.

Return EINVAL in sysfs instead.

These security_ops are declared like

        int (*inode_mknod) (struct inode *dir, struct dentry *dentry,
                            int mode, dev_t dev);

with a mode and a dev_t argument.

But the users mistakenly had major, minor instead of mode, dev.

Given Andi Kleen's patch that introduces of VFS-level support for
nanosecond time resolutions, we should finally be able to export the
existing NFS client level support to userland.

In order to do so, the following patch will convert all NFS private 'raw
u64' values into the kernel-supported struct timespec directly in the
xdr_encode/xdr_decode routines.

It adds support for the nanosecond field in NFS 'setattr' calls, and in
nfs_refresh_inode().

Finally, there are a few cleanups in the nfs_refresh_inode code that
convert multiple use of the NFS_*(inode) macros into a single
dereference of NFS_I(inode).

Since I believe kallsyms is important, this reimplements it sanely,
using the current module infrastructure, and not using an external
kallsyms script.

FYI, the previous interface was:

int kallsyms_symbol_to_address(
	const char       *name,			/* Name to lookup */
	unsigned long    *token,		/* Which module to start with */
	const char      **mod_name,		/* Set to module name or "kernel" */
	unsigned long    *mod_start,		/* Set to start address of module */
	unsigned long    *mod_end,		/* Set to end address of module */
	const char      **sec_name,		/* Set to section name */
	unsigned long    *sec_start,		/* Set to start address of section */
	unsigned long    *sec_end,		/* Set to end address of section */
	const char      **sym_name,		/* Set to full symbol name */
	unsigned long    *sym_start,		/* Set to start address of symbol */
	unsigned long    *sym_end		/* Set to end address of symbol */
	);

The new one is:
/* Lookup an address.  modname is set to NULL if it's in the kernel. */
const char *kallsyms_lookup(unsigned long addr,
			    unsigned long *symbolsize,
			    unsigned long *offset,
			    char **modname);
