Allocations of pages below the min watermark run a risk of the

This patch removes the check for pfmemalloc from the alloc hotpath and
puts the logic after the election of a new per cpu slab. For a pfmemalloc
page we do not use the fast path but force the use of the slow path which
is also used for the debug case.

This is needed to allow network softirq packet processing to make

Currently softirq context cannot use PF_MEMALLOC due to it not being
associated with a task, and therefore not having task flags to fiddle

If swap is backed by network storage such as NBD, there is a risk

It could happen that all !SOCK_MEMALLOC sockets have buffered so

Currently swapfiles are managed entirely by the core VM by using ->bmap

The patch "mm: Add support for a filesystem to activate swap files and

direct_IO() handler.

GFP_NOFS is _more_ permissive than GFP_NOIO in that it will initiate
