Rusty, have a quick look at virtio_net wrt. the changes I
made to skb_to_sgvec()'s behavior. I think I might have
even fixed something :-)
Jens, please review my commentary wrt. sg_mark_end() and
it's nonintuitive behavior which led to these bug
Bug is in the new dev_ifname32:
uifr = compat_alloc_user_space(sizeof(struct ifreq));

There's a stray ";" after the if statement, that was obviously not

Allow PF_MEMALLOC to be set in softirq context. When running softirqs from
a borrowed context save current->flags, ksoftirqd will have its own
task_struct.

Failing to allocate a cache entry will only harm performance not correctness.
Do not consume valuable reserve pages for something like that.

Provide an a_ops->swapfile() implementation for NFS. This will set the
NFS socket to SOCK_MEMALLOC and run socket reconnect under PF_MEMALLOC as well
as reset SOCK_MEMALLOC before engaging the protocol ->connect() method.
PF_MEMALLOC should allow the allocation of struct socket and related objects
GFP_ATOMIC failures are rather common, no not warn about them.

With the introduction of the shared dirty page accounting in .19, NFS should
not be able to surpise the VM with all dirty pages. Thus it should always be
able to free some memory. Hence no more need for mempools.

Do as Trond suggested:

Disable NFS data cache revalidation on swap files since it doesn't really
make sense to have other clients change the file while you are using it.
Thereby we can stop setting PG_private on swap pages, since there ought to
be no further
Hi,
Another posting of the full swap over NFS series.
[ I tried just posting the first part last time around, but
that just gets more confusion by lack of a general picture ]
[ patches against 2.6.23-mm1, also to be found online at:
http://programming.kicks-ass.net/kernel-patches/vm_deadlo
Add some packet-split receive hooks.
For one this allows to do NUMA node affine page allocs. Later on these hooks
will be extended to do emergency reserve allocations for fragments.

Generic reserve management code.
It provides methods to reserve and charge. Upon this, generic alloc/free style
reserve pools could be build, which could fully replace mempool_t
functionality.

It could happen that all !SOCK_MEMALLOC sockets have buffered so much data
that we're over the global rmem limit. This will prevent SOCK_MEMALLOC buffers
from receiving data, which will prevent userspace from running, which is needed
to reduce the buffered data.
Fix this by exempting the SOCK_MEMA
There is a small race between the procfs caller and the memory hotplug caller
of setup_per_zone_pages_min(). Not a big deal, but the next patch will add yet
another caller. Time to close the gap.

Add reserves for INET.
The two big users seem to be the route cache and ip-fragment cache.
Reserve the route cache under generic RX reserve, its usage is bounded by
the high reclaim watermark, and thus does not need further accounting.
Reserve the ip-fragement caches under SKB data reserve, thes
Restrict objects from reserve slabs (ALLOC_NO_WATERMARKS) to allocation
contexts that are entitled to it.
Care is taken to only touch the SLUB slow path.
This is done to ensure reserve pages don't leak out and get consumed.

In order to make sure emergency packets receive all memory needed to proceed
ensure processing of emergency SKBs happens under PF_MEMALLOC.
Use the (new) sk_backlog_rcv() wrapper to ensure this for backlog processing.
Skip taps, since those are user-space again.

A new addres_space_operations method is added:
int swapfile(struct address_space *, int)
When during sys_swapon() this method is found and returns no error the
swapper_space.a_ops will proxy to sis->swap_file->f_mapping->a_ops.
The swapfile method will be used to communicate to the address_spa
Factor out the gfp to alloc_flags mapping so it can be used in other places.

Toss all emergency packets not for a SOCK_MEMALLOC socket. This ensures our
precious memory reserve doesn't get stuck waiting for user-space.
The correctness of this approach relies on the fact that networks must be
assumed lossy.

the reserve when needed. SKBs allocated from the reserve are tagged in
skb->emergency.
Teach all other skb ops about emergency skbs and the reserve accounting.
