Fix multicast packet transmit logic to account for repetitive transmission
of single skb:
- correct check for available buffers (this bug may produce NULL pointer
  crash dump in case of heavy traffic);
- update skb user count (incorrect user counter causes a warning dump from
  net_tx_action routine during multicast transfers in systems with three or
  more rionet participants).

proc_get_inode() obtains the inode via a call to iget_locked().
iget_locked() calls alloc_inode() which will call proc_alloc_inode() which
clears proc_inode.fd, so there is no need to clear this field in

If iget_locked() instead found the inode via find_inode_fast(), that inode

Some coredump handlers want to create a core file in a way compatible with

handler to know that the process being dumped was suid'ed.

This patch adds the new %d specifier for format_corename() which simply
reports __get_dumpable(mm->flags), this is compatible with

The original model of device_cgroup is having a whitelist where all the
allowed devices are listed. The problem with this approach is that is
impossible to have the case of allowing everything but few devices.

The reason for that lies in the way the whitelist is handled internally:
since there's only a whitelist, the "all devices" entry would have to be
removed and replaced by the entire list of possible devices but the ones
that are being denied.  Since dev_t is 32 bits long, representing the allowed
devices as a bitfield is not memory efficient.

This patch replaces the "whitelist" by a "exceptions" list and the default
policy is kept as "deny_all" variable in dev_cgroup structure.

The current interface determines that whenever "a" is written to devices.allow
or devices.deny, the entry masking all devices will be added or removed,
respectively. This behavior is kept and it's what will determine the default
policy:

	# cat devices.list
	a *:* rwm
	# echo a >devices.deny
	# cat devices.list
	# echo a >devices.allow
	# cat devices.list
	a *:* rwm

The interface is also preserved. For example, if one wants to block only access
to /dev/null:
	# ls -l /dev/null
	crw-rw-rw- 1 root root 1, 3 Jul 24 16:17 /dev/null
	# echo a >devices.allow
	# echo "c 1:3 rwm" >devices.deny
	# cat /dev/null
	cat: /dev/null: Operation not permitted
	# echo >/dev/null
	bash: /dev/null: Operation not permitted
	mknod /tmp/null c 1 3
	mknod: `/tmp/null': Operation not permitted
	# echo "c 1:3 r" >devices.allow
	# cat /dev/null
	# echo >/dev/null
	bash: /dev/null: Operation not permitted
	mknod /tmp/null c 1 3
	mknod: `/tmp/null': Operation not permitted
	# echo "c 1:3 rw" >devices.allow
	# echo >/dev/null
	# cat /dev/null
	# mknod /tmp/null c 1 3
	mknod: `/tmp/null': Operation not permitted
	# echo "c 1:3 rwm" >devices.allow
	# echo >/dev/null
	# cat /dev/null
	# mknod /tmp/null c 1 3

A section with the name "Example" (case-insensitive) has a special meaning
to kernel-doc.  These sections are output using mono-type fonts.  However,
leading whitespace is stripped, thus robbing a lot of meaning from this,
as indented code examples will be mangled.

This patch preserves the leading whitespace for "Example" sections.  More
accurately, it preserves it for all sections, but removes it later if the

one that cannot be traced back to the filesystem root.

Add a new msdos/vfat binary mount option "nfs" so that FAT filesystems

index they will never use.

Finally, simplify NFS file handle generation and lookups.  An

Under memory pressure, the system may evict dentries from cache.  When the
FAT driver receives a NFS request involving an evicted dentry, it is
unable to reconnect it to the filesystem root.  This causes the request to
fail, often with ENOENT.

This is partially due to ineffectiveness of the current FAT NFS
implementation, and partially due to an unimplemented fh_to_parent method.
 The latter can cause file accesses to fail on shares exported with
subtree_check.

This patch set provides the FAT driver with the ability to
reconnect dentries.  NFS file handle generation and lookups are simplified
and made congruent with ext2.

Testing has involved a memory-starved virtual machine running 3.5-rc5 that
exports a ~2 GB vfat filesystem containing a kernel tree (~770 MB, ~40000
files, 9 levels).  Both 'cp -r' and 'ls -lR' operations were performed
from a client, some overlapping, some consecutive.  Exports with
'subtree_check' and 'no_subtree_check' have been tested.

Note that while this patch set improves FAT's NFS support, it does not
eliminate ESTALE errors completely.

The following should be considered for NFS clients who are sensitive to ESTALE:

* Mounting with lookupcache=none
  Unfortunately this can degrade performance severely, particularly for deep
  filesystems.

* Incorporating VFS patches to retry ESTALE failures on the client-side,
  such as https://lkml.org/lkml/2012/6/29/381

* Handling ESTALE errors in client application code

This patch:

Move NFS-related code into its own C file.  No functional changes.

    drivers/rtc/rtc-m41t80.c:308:12: warning: 'm41t80_rtc_read_alarm' defined but not used [-Wunused-function]

Remove these functions (and the commented out references to them) to
silence these warnings.  Anyone wanting to fix the alarm irq functionality
can easily find the removed code in the git log of this file or through
some web searches.

As RTC driver needs only irq number from platform data, using
platform_get_irq(), instead of generic dev_get_platdata().
