Linux v2.5.56

Linux v2.5.56

[Linus Torvalds]

Trying to make releases slightly more often and slightly smaller.

ACPI, USB, networking (mainly netfilter) updates. Some syscall path
updates and a thread bug in mm_release() that would miss updating the TID
and cause a few extra traps at exec time.

And a watchdog forward port from 2.4.x by DaveJ.

			Linus

Presumably one of your filesystems is using htree (indexed directories).
It's a bug - nobody has found it yet.

The modestly good news is that I have found a workload which triggers it in
ten minutes, but I have not looked into it at all.

The modestly bad news is that e2fsprogs-1.32's mke2fs enables htree by
default.  It really shouldn't be doing that - htree isn't ready yet.

Use

	dumpe2fs -h /dev/hda1 | grep dir_index

to see if htree is enabled.

Use

	tune2fs -O '^dir_index' /dev/hda1

to disable it.


There are no trmendously bad bugs in htree.  Mainly this one (which _could_
cause crashes and scribbled directories) and a small memory leak on each
unlink.

I can take care of that, although i think this driver could be removed due 
scx200_wdt.c supporting the same hardware. I'll look into it.

Yup, it didn't before I poked it too, it needs updating to the new PNP-fu

just to stem the number of 'this still isnt finished' reports I'm
getting, I'm working through the 2.4 diffs incrementally. I'm not
done yet, so please, be patient..
