The attached patch illustrates how the new attribute functions can be
used.

The 53c700 modifies the queue_depth attribute so it can be set by the
root user, and also adds a new active_tags attribute which may be used
to obtain the information it currently puts out via its proc interface.

This achieves all I think we really need, which is the ability to have
LLDs provide their own routines for setting the default attributes.

The attached patch makes the sysfs attributes a property of the host
template (I can't really see a reason why the actual attributes need to
change per host, so I think the template is the better place for them).

I've also provided helper functions to modify the attributes in the LLD
init routines.

The host variable is now passed in, so we shouldn't have a
similar variable defined in the proc_info routine

Request port before using it.

Yeah, I know the method is obsolete but for proper refcounting we
need to get rid of all those scsi_host_hn_get() abusers.

scsi_host_hn_get() and scsi_host_put() are not exported anymore
after this patch.

This is a catch up, applying the patch that Andries
Brouwer sent a while back. It will apply to lk 2.5.69
and 2.5.69-bk10 .

this fix makes sure that all test in irq handling in that
driver are for NULL thus fixing an oops.

In the sysfs scsi host reference counting merge the call to a legacy hosts
release function was removed.

This patch adds the call back in.

This patch was tested with insmod / rmmod on LLDDs using the legacy interface
and LLDDs using the new interface:

Legacy Interface:
qla2xxx-v8.00.00b1
qlogicisp
aic7xxx_old (Does not call scsi_unregister in release, but unloaded)

New Interface:
scsi_debug
aic7xxx (Many illegal context warnings caused by mid vs LLDD primitive
         mixing, but appears to unload clean).

This fixes the problem that adapter id's are not the minor number for the
i2c-dev devices anymore.  Also adds a i2c-dev class to let userspace know
which i2c-dev device is bound to which i2c adapter.

Noticed by Julie DeWandel <jdewand@redhat.com>.

do_fork() needs to return the pid (or error), not the pointer to the
resulting process structure.  The process structure may not even be
valid any more, since do_fork() has already woken the process up (and as
a result it might already have done its thing and gone away).

Besides, doing it this way cleans up the users, which all really just
wanted the pid or error number _anyway_.

This fixes the x86 users, other architectures need to be fixed up as
well.

A familar type of Oops: d_path() can return an error ENAMETOOLONG, and
if we fail to test a segfault occurs.

So we must test.  What we do is a different matter.  Rather arbitrarily
I return the string " (too long)" for use in /proc/mounts.

Several SCSI drivers confuse CHECK_CONDITION and CHECK_CONDITION << 1.
One of them is NCR5380.c. Below a patch adding status_byte() twice.

(On the other hand, sun3_NCR5380.c does this right, and generally
looks better. Maybe they can be merged eventually.)

After

    # mount --rbind /tmp /mnt

(on 2.5.68) I have a corrupted namespace. Umounting /mnt fails,
and /proc/mounts contains

    ...
    /dev/root /mnt ext3 rw 0 0
    proc /mnt/proc proc rw 0 0
    usbfs /mnt/proc/bus/usb usbfs rw 0 0
    /dev/hdb5 /mnt/usr reiserfs rw 0 0
    ...

where of course no directories /mnt/proc or /mnt/usr exist.

This is caused by the fact that copy_tree() thinks that the dentry
it is called with is the root of the filesystem. If it is not,
confusion arose.

This patch fixes this confusion.

- Fix possible memory leak in iso.c
- Added handling for more than 1 Logical_Unit_Number entry in a unit
  directory for SBP-2. This allows for handling the second type of LUN
  that we didn't support yet.

This fixes a race noticed by Mike Galbraith: the scheduler can lose a
rebalance tick if some task happens to not be rescheduled in time.  This
is not a fatal condition, but an inconsistency nevertheless.
