The afs filesystem driver allows unstarted operations to be cancelled by
signal, but most of these can easily be restarted (mkdir for example). The
primary culprits for reproducing this are those applications that use
SIGALRM to display a progress counter.
File lock-extension operation is marked
Implement the "will_modify" parameter passed to fscache_use_cookie().
Setting this to true will henceforth cause the affected object to be marked
as dirty on disk, subject to conflict resolution in the event that power
failure or a crash occurs or the filesystem operates in disconnected mode.

Provide a cache operation to resize an object. This is intended to be run
synchronously rather than being deferred as it really needs to run inside
the inode lock on the netfs inode from ->setattr() to correctly order with
respect to other truncates and writes.

Replace the object management state machine with something a lot simpler.
The entire process of setting up or tearing down a cookie is done in one
go, and the dispatcher either punts it to a worker thread, or if all the
worker threads are all busy, does it in the current thread.
Recast assertion in terms of cookie not being an index rather than being a

The default is still set to inode32 for backwards compatibility, but
system administrators can opt in to the new 64-bit inode numbers by
either:
1. Passing inode64 on the command line when mounting, or
2. Configuring the kernel with CONFIG_TMPFS_INODE64=y
The inode64 and inode32 names are used
In Facebook production we are seeing heavy i_ino wraparounds on tmpfs.
On affected tiers, in excess of 10% of hosts show multiple files with
different content and the same inode number, with some servers even
having as many as 150 duplicated inode numbers with differing file
content.
This causes
get_next_ino has a number of problems:
- It uses and returns a uint, which is susceptible to become overflowed
if a lot of volatile inodes that use get_next_ino are created.
- It's global, with no specificity per-sb or even per-filesystem. This
means it's not that difficult to cause inode

Until we tell ACPI that we support generic initiators, it will have
to operate in fall back domain mode and all _PXM entries should
be on existing non GI domains.
This patch sets the relevant OSC bit to make that happen.

In common with memoryless domains we only register GI domains
if the proximity node is not online. If a domain is already
a memory containing domain, or a memoryless domain there is
nothing to do just because it also contains a Generic Initiator.

Generic Initiators are a new ACPI concept that allows for the
description of proximity domains that contain a device which
performs memory access (such as a network card) but neither
host CPU nor Memory.
This patch has the parsing code and provides the infrastructure
for an architecture to

or remove the extra parameter in acpi_map_pxm_to_node.
Introduces a new type of NUMA node for cases where we want to represent
the access characteristics of a non CPU initiator of memory requests,
