From Alexey: teach the 3com ethernet driver to add checksums to
outgoing UDP frames.

The ramdisk address_space needs to have a non-zero
mapping->backing_dev_info.memory_backed, so it doesn't contribute to
global memory accounting.

At present it is confusing memory accounting and causing
balance_dirty_pages to go into an infinite loop.

If you use scsi_debug the patch below fixes a problem that has existed
since the updated scan code was merged in. scsi_debug previously assumed
that the scsi_device used to probe and the device permanently added to the
host_queue would be the same. This caused scsi_debug to allocate some
internal data and key it off the scsi_device pointer for later use.  This
resulted in scsi_debug failing all IO post scanning. This patch corrects
this problem.

Note:
	Douglas Gilbert is the maintainer of this driver.
	dougg@gear.torque.net
	http://www.torque.net/sg/

	During Douglas Gilbert's time-off he connects when he can so it
	maybe a bit until he can address this.

	In the interim this patch makes scsi_debug functional.

This patch consolidates the setting of the LUN in byte 1 of the SCSI
command block for SCSI-2 and lower devices.

This is needed for multi-path IO (some devices can actually have differnt
LUN values for each path), but is also a nice clean up of the code.

sg.c was able to inhibit setting the value, this removes that capability -
if it is really needed it can be black listed in the device_list[] flags,
or sg could set a similiar flag.

This is patched against the latest bk (as of some time on Oct 16), and
patches clean against 2.5.43.

Tests were run with different adapters and various disks and a tape drive,
I have no SCSI-2 multi-lun devices, so the main verifcation was done using
a modified scsi_debug.c driver to emulate a multi-lun SCSI-2 device.

This does the following three things:

 (1) Makes the functions in mm/readahead.c only use struct file* to pass to
     readpage(). address_mapping* and file_ra_state* are used instead to keep
     track of readahead stuff.

 (2) Adds a new function do_generic_mapping_read() that is similar to
     do_generic_file_read(), except that it uses a mapping pointer and a
     readahead state pointer to access a file. The file* is only used to pass
     to readpage().

 (3) Turns do_generic_file_read() into an inline function in linux/fs.h that
     simply wraps do_generic_mapping_read().

This should mean that it is no longer necessary to have a struct file to
access a file in this manner. Just an inode or address space should be
sufficient.

It also means alternate read-ahead structures can be maintained.

The reason I want this is that I'm writing a general cache manager for
filesystems such as AFS, NFSv4, and Lustre. Block devices are made available
to the "cache manager" by means of a filesystem that can be mounted. I'm
storing meta data in an inode in the cache, but to scan this at the moment I
need to gain a "struct file" to use with do_generic_file_read().

This involves either creating a dummy dentry and struct file (which will cause
Al Viro to come looking for me with a shotgun), or to use an extra auxilliary
filesystem mounted with do_kern_mount(), neither of which are particularly
appealing.

This patch is the alternative... it provides a function that I can pass an
address_space to. This also allows me to make use of readahead semantics
without having to reinvent them for myself.

In the initial discussion LSM folks agreed on this, the
rationale is that lsseek itself makes no sense to
project as mmap() and pread/pwrite() allow access to any
area of the file anyway.

These exports have the power to change the implementations of all
syscalls and I've seen people exploiting this "feature".

Make the exports GPLonly (which some LSM folks agreed to
when it was merged initially to avoid that).

If you read my previous post on this patch I indicated that few of the
driver changes I was only able to compile test ( block/cciss_scsi.c,
scsi/53c700.c, scsi/pcmcia/*, scsi/wd33c93.c). The changes to the
drivers are to remove the old interfaces and possibly extra NULL inits
of struct members. These changes will need to be ok'd by there
respective maintainers. I did receive feedback from two.

I have tested these changes on ips, aic, qlogicisp, and scsi_debug
drivers.

This is a resend of my previous patch clean ups to the scsi_host lists.

	* Made function naming consistent with rest of SCSI
	* Corrected a problem with driverfs registration to early. Also
	  changed from put_device to device_unregister.
        * Fixed a regression in my previous patch that the scsi_host
          list was not sorted by host number. When we get some device
          naming this hack can be removed.
        * Switch scsi host template, name, host lists to struct
          list_head's.
        * Moved all scsi_host related register / unregister functions
          into hosts.c
        * Added list accessor interface and created a function similar
          to driverfs bus_for_each_dev.

xfs_alloc_put_freelist marks the blocks it gets as "busy".  However, this
function is used in two different ways:
   
  1.  xfs_alloc_fix_freelist calls xfs_alloc_put_freelist to add new
  blocks to the freelist (that is, blocks it allocated with
  xfs_alloc_ag_vextent).
   
  2.  xfs_alloc_delrec calls xfs_alloc_put_freelist to free deleted
  b+tree blocks.  
   
In case 1, the blocks should not be on the busy list; in case 2, they
should.
