This chunk is present in 2.4, missing in 2.5.  It
stops the loop thread from waiting on its owm buffers.

It's up to other architectures to worry about portability for now.

Moved i_sem down into notify_change() and out of the UMSDOS
function. Moved BKL down from notify_change into filesystems.

typo in that last patch, sorry.

This increases the max read/write size for nfsd from 8K to 32K.

This requires making NFSv2 return the right number in statfs
requests.  NFSv3 already does that.

[PATCH] PATCH 3 of 4 : knfsd : Store the fsid in the returned attributes instead of the device number

When a filesystem is exported with  fsid=  we should use that
fsid instead of the i_dev number when returning NFS attributes,
so that there is no chance of clients that depend on the filesys
id in the attributes getting confused by device numbers changing.

We only do this if the reference filehandle uses fsid to identify
the filesystem, so that a server can be converted from non-fsid= to
using fsid= without confusing active clients.

Previously we could only export FS_REQUIRES_DEV filesystems
as we need a devno to put in the filehandle.
Now that we have fsid= (NFSEXP_FSID) we don't need a devno
to put in the filehandle so we can relax this requirement.

Use symbolic names for some common size components in the response
size calculation for the NFSD.  This makes it easier to get the
numbers right and to review them.
This patch also fixes a few number for nfsv3 that were wrong.

Lets just kill this check -- it usually only catches drivers queueing
something in front of a started request on their own (such as shoving a
request sense in front of a failed packet command, for instance). So
it's either working around this detection in some drivers, or killing
it. I vote for the latter, patch attached against 2.5.8-pre1 :-)

moved the USB_STORAGE Config.help items into the drivers/usb/storage directory.

into penguin.transmeta.com:/home/penguin/torvalds/repositories/kernel/linux

added a README file to explain what the different subdirectories are for.

moved class/storage/ back to storage/
created input/
orderd the makefiles and config.in menus better.
