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).

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.

plus other small cleanups, in particular getting rid of
isdn_ppp_{receive,send}_ccp() and calling into the CCP code directly.

No (well, hardly any ;) code changes, only moving all /dev/ipppX related
code next to each other and some indenting changes.

o Now that all the infrastructure is in place, struct ipppd can
  easily be allocated when /dev/ipppX is opened and freed
  in the destructor.
o Separate the mix of state and flags in struct ipppd::state.
  We only have three states, open, assigned and connected, and
  additionally two flags to jump out of poll(), returning POLLHUP /
  POLLIN.

Instead of just recording the slot number and then retrieving
the ipppd via that, we can now just keep a pointer and get a
reference which makes sure that it does not go away until
we drop the reference.

We had introduced ipppd_get/put() earlier, so now add a real reference
count.

Basically, all what was missing was a common way to xmit frames
given the isdn_net_dev / isdn_net_local. We have this now by means
of function pointers (still room for improvement there, though), so
now let's do things from isdn_ppp_ccp.c.

Let isdn_ppp_ccp.c take care of keeping state / flags by itself.

Use a shared function for generating the PPP header, use the
{put,get}_u{8,16,32} helpers for endian-safe access.

I cannot see now reason why ISDN PPP devices should have a fake
::header routine which reserves a couple of bytes just to reclaim them
later during hard_start_xmit(), and since it works just as well without
it...

Fix missed STAT_BSENT acks and don't use skb_clone() for the skb which is
sent back, the network layer gets confused by that.

Create the new files isdn_ppp_ccp.[hc] which deal with PPP CCP
(compression control protocol) related stuff. Move most of the CCP
related stuff from isdn_ppp.c into isdn_ppp_ccp.c, putting CCP
state into a new "struct ippp_ccp".

A lot of the state in struct ipppd actually belongs to
isdn_net_dev or isdn_net_local, making it more easily accessible at a
most places, and also removing the ambiguity whether it's link-
or bundle-specific.

and move the declaration from include/linux/isdn_ppp.h
into drivers/isdn/i4l/isdn_ppp.c

Make sync PPP compile with the latest changes to the ISDN net device
layer - PPP negotiations work again after this patch.

Definitions which is only needed in one source file should go there and not
in a common header.

Last step in separating generic / interface-type specific code,
the former is now all in isdn_net_lib.c, the specific code in
isdn_net.c / isdn_ppp.c / isdn_concap.c

Instead of using locking per-channel, just lock the entire ISDN net work
interface as an entity, getting rid of weird locking.
  
Basically, ::hard_start_xmit() is already serialized by the network core,
so we could just rely on that. However, we want to send keep alive
frames, PPP messages from ipppd and such things directly without going
through the network stack, so we additionally lock
isdn_net_local->xmit_lock in hard_start_xmit(), which is taken in
the other paths dealing with transmitting frames as well.

If you compile the kernel with -ffunction-sections, each function gets
put in a section .text.function_name.  This collides with our current use
of .text.init.  So here's a patch which converts x86 to use .init.text
instead.

I've tested it on x86 and it still frees 120k of ram, so it seems to work.
Other architectures will need to change their vmlinux.lds appropriately,
and may need other changes (arm, m68k seem to use .text.init verbatim).

[PATCH] md - 1 of 1 - Register mergeable function for linear so requests don't cross device boundries

We abstract out "which_dev" which finds which device a sector is on
and us it to make sure both ends of a to-be-merged request will
be on the same device.

As the expkey cache references entries in export cache,
it should be flushed first.
Also, the auth_unix caches should go last.

This brings the linux-2.5.42 tree up to spec WRT setclientid and
