[Andrew Morton]

ftp://ftp.kernel.org/pub/linux/kernel/people/akpm/patches/2.6/2.6.8-rc1/2.6.8-rc1-mm1/

- Lots of little fixes, mainly

- Numerous scheduling latency fixes, mainly in the ext3 area.

  This is a first pass - these patches need redoing and a bit of
  infrastructure consolidation.

- Outta here: I won't be in a position to handle patches until July 26.  Off
  to http://www.tech-forum.org/upcoming/open_source_software_06-10-04.htm and
  then Kernel Summit and then OLS.

This kernel runs like a dessicated slug if you have more than 2G of memory
due to a 32-bit overflow.

Dentry cache hash table entries: 1 (order: -10, 4 bytes)
Inode-cache hash table entries: 1 (order: -10, 4 bytes)

The dcache is a singly-linked list.  Here's a (lame) fix:

btw, David, I'm wondering about this loop:

	do {
		size = bucketsize << log2qty;

		table = (void *) alloc_bootmem(size);

	} while (!table && size > PAGE_SIZE);

Is this a busy-wait-until-someone-plugs-in-more-ram-chips thing? ;)

I assume you meant something like the above?

btw, that (void *) cast was superfluous...

Well, with IBM hardware, you never know:-)

Yeah... that got fixed here in my 2.4 version, and I failed to transfer the
fix across. log2qty should be decremented every time around the loop:

-	} while (!table && size > PAGE_SIZE);
+	} while (!table && size > PAGE_SIZE && --log2qty);

[patch] 2.6.8-rc1-mm1: USB w9968cf compile error

This patch marks w9968cf_valid_depth as inline, although it's used 
before it's defined.

gcc 3.4 therefore correctly fails with:

<--  snip  -->

...
  CC      drivers/usb/media/w9968cf.o
drivers/usb/media/w9968cf.c: In function `w9968cf_set_picture':

make[3]: *** [drivers/usb/media/w9968cf.o] Error 1

<--  snip  -->


This patch moves w9968cf_valid_depth above it's first user (it also uses 
two other functions to keep the ordering of functions a bit more 
consistent).

I tested this...
   With HZ=1000:
     - normal boot: calibrate_delay() took 23 milliseconds
     - specifying lpj=xxx: calibrate_delay() took 43 microseconds.
   With HZ=100:
     - normal boot: calibrate_delay() took 264 milliseconds
     - specifying lpj=xxx: calibrate_delay() took 43 microseconds.

No adverse behaviour was observed.

This will be a big improvement for embedded folks.

It oopses if you try to write on a CDRW without media loaded. Who would do
such a stupid thing ? Me the impatient trying to write before the drive ends
to load the disc...

The bad thing is that it leaves the drive in an ususable state:

Error trying to open /dev/hdc exclusively (Device or resource busy)... retrying in 1 second.
Error trying to open /dev/hdc exclusively (Device or resource busy)... retrying in 1 second.

It does not happen with 2.6.8-rc2. I am not using a pure rc1-mm1, but applied
all the patches neded to build with gcc-3.4.1:

- fix for usb-locking
- sg.c changes to use standard jiffies
- inline corrections from Adrian Bunk for e1000, smp, sunrpc, eth1394.

Yup, nvidia loaded, but does it really matter ?
