I've been carrying this since Jan sent it out a month or two ago.
I don't know if anyone has tested it though.  The sort of people
who use quotas tend to like nice stable kernels.  I read through it,
but can't say that I know enough about quotas to know if it makes sense.
The wait_on_dquot() synchronisation is a bit odd.

I do need to do a round of stability testing with this and ext3 - the
interaction between quotas and ext3 is an area where we've had deadlocks
in the past.

But the quota locking is definitely looking crufty, and I'd suggest that
we run with this..


Patch from Jan Kara <jack@suse.cz>

"I'm resending you the patch with new quota SMP locking.  The patch removes
 BKL and replaces it with two spinlocks protecting quota lists and data
 stored in dquot structures.  Also non-SMP locking was changed a bit make SMP
 locking easier (eg.  we got rid of not very nice dq_dup_ref counters).  The
 patch is against 2.5.48 but applies well also to 2.5.49.  Would you please
 apply the patch?"


- Change dqoff_sem from a semaphore to an rwsem.

- Convert dqi_flags from an int to a ulong and use test_bit/set_bit rather
  thatn &/|

- The various exported quota operations now run without lock_kernel().
  This means that things like DQUOT_ALLOC_SPACE no longer take lock_kernel()
  in out high-perfomance filesystems.  Nice.

- Replace lock_kernel() in the quota code with two quota-private global
  locks.

- Replace all the open-coded waitqueue management with a semaphore
  (wait_on_dquot())

There's a bunch of useless MOD_INC_USE_COUNT/MOD_DEC_USE_COUNT in
ppp-related code when it manipulates the use count in functions
that are only called from other modules, i.e. it's locked in by
the depencies anyway.  Get rid of it.

As already state in the thread about Adam's devfs reimplementation there
is much devfs functionality that is unused or only used by the
arch/ia64/sn/ code that currently doesn't even compile in 2.5 and that
will get it's own filesystem that fits the needs better when SGI moves
to 2.6.

(the first hunk is the only exception to the above rule, but it's just
a debug printk :))

fs.h only needs the forward-declaration of struct statfs

This upgrades the Fusion-MPT driver from 2.03.00.02 to 2.03.01.01.

Bug Fixes:
 o Added back missing queuecommand entry point define ?!
 o Added to code to break marriage of two controllers during unload
  (could cause a panic)
 o SCSI driver will de-register with base driver if no SCSI-capable
   adapters found

Minor Changes:
 o Removed errant spaces at ends of lines  (most of the changes)
 o Moved code around (and in-lined) some functions for performance reasons.
 o Modified /proc functionality to facilitate testing with 2.5
 o Added a call to synchronize_irq on unload (HP request)
 o Modified load of base to close a potential hole
 o Added code to set the FW IO coalescing depth (IBM request)
 o Changed return when mptctl driver registration fails (Kernel.org request)
 o SCSI driver detect routine calls a generic spinlock for all kernels
   (Kernel.org request)
 o Controller RAID page dynamic instead of static

Currently running a multi-disk stress test w/ 2.5.53,  this patch and driver
built-in. Verified basic reset handling is working properly.

Showing the logo on every open became annoying. I leave it up to the driver writers when they want to display the logo. Fo embeded devices it probably is wise to have them set there mode themselves then display the logo to let them know if the hartdware worked. FOnt header file location changed.

on the end of __GNUC_MINOR"

James Bottomley confirmed the "deprecated" attribute requires gcc 3.1
and onward, not gcc 3.0.

This updates the check in compiler.h accordingly.

Atari NCR5380 SCSI driver tag bitmap updates:
  - Use DECLARE_BITMAP() to declare the tag bitmap
  - Remove `MAX_TAGS must be a multiple of 32', which is no longer true
  - Declare and use CLEAR_BITMAP() to set all bits in a bitmap to zero
  - Fix bitops call problems that got unnoticed before

Now that we have a unique suffix for kernel modules (.ko), we
can extend to former "make some/object.o" to work for kernel modules
as well, even composite ones.

It's as easy as "make some/dir/module.ko".

Moved archhelp to arch/x86_64/Makefile
Introduced usage of $(build) and $(clean)
Use kbuild clean infrastructure

Moved archhelp to arch/sparc64/Makefile
introduced usage of $(build)
Removed superflous targets archclean and archmrproper

Moved archhelp to arch/arm/Makefile
Introduced usage of $(build) and $(clean)

arch/$(ARCH)/Makefile already contains the kbuild required additions
to allow the kernel to be built for the architecture in question.
Moving archhelp centralise this information, and no longer require a
boot directory to exist to utilise this feature.
  
Update i386 to define archhelp in arch/$(ARCH)/Makefile
Other architectures will be updated in next cset.

The former macro $(descend ...) hide for make the fact that a recursively make was
invoked. The replacement $(Q)$(MAKE) -f scripts/Makefile.build obj=dir was too verbose.
  
Introduced $(build) and $(clean) allowing the following syntax:
$(Q)$(MAKE) $(build)=arch/i386/boot target
and similar for clean.
  
Introduced $(build) and $(clean) in general, and for i386 architecture.

Add $(srctree)/ etc. to some more places where it was still missing.

Speeds up rendering of text by around 7x for 8bpp cards,
as you'd expect from the difference in the volume of data
passed across the bus.  Thus the win should be about 31x
for 32bpp cards.

The generated .tmp_kallsyms.S needs to use .long / .quad for
32/64 bit archs. To know which arch we're compiling for, we
use the preprocessor and BITS_PER_LONG from <asm/types.h>.

Unfortunately, asm/types.h was not safe to include from assembler
files, so lots of #ifndef __ASSEMBLY__ needed to be added - should
be fine now, untested for != i386, though.
