To be able to use this, a recent nfsutils package is required.

Add an address space operation to write one single page of data to an inode at
a page-aligned location (thus permitting the implementation to be highly
optimised). The data source is a single page.
This is used by CacheFiles to store the contents of netfs pages into their
backing file pages.

Thereby we can stop setting PG_private on swap pages, since there ought to

Are you looking for more that what is in Next/merge.log in the tree?

Change the skb allocation api to indicate RX usage and use this to fall back to
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.
Use the (new) packet split API to allocate and track
Introduce sk_allocation(), this function allows to inject sock specific
flags to each sock related allocation.

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.

Change ALLOC_NO_WATERMARK page allocation such that the reserves are system
wide - which they are per setup_per_zone_pages_min(), when we scrape the
barrel, do it properly.

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
Replace all relevant occurences of page->index and page->mapping in the NFS
client with the new page_file_index() and page_file_mapping() functions.

Avoid memory getting stuck waiting for userspace, drop all emergency packets.
This of course requires the regular storage route to not include an NF_QUEUE
target ;-)

Implement all the new swapfile a_ops 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

Hi,
Another posting of the full swap over NFS series.
Andrew/Linus, could we start thinking of sticking this in -mm?

In order to teach filesystems to handle swap cache pages, two new page
functions are introduced:
pgoff_t page_file_index(struct page *);
struct address_space *page_file_mapping(struct page *);
page_file_index - gives the offset of this page in the file in PAGE_CACHE_SIZE
blocks. Like
Provide the basic infrastructure to reserve and charge/account network memory.
We provide the following reserve tree:

2)network TX reserve
3) protocol TX pages
4)network RX reserve
5) SKB data reserve

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.
