What: ip_queue
Date: finally removed in kernel v3.5.0
Contact: Pablo Neira Ayuso <pablo@netfilter.org>
Description:
ip_queue has been replaced by nfnetlink_queue which provides
more advanced queueing mechanism to user-space. The ip_queue
module was already announced to become obsolete years ago.

d_alloc_root() is gone, along with a lot of bugs caused by code
misusing it. Replacement: d_make_root(inode). The difference is,
d_make_root() drops the reference to inode if dentry allocation fails.

The witch is dead! Well, 2/3 of it, anyway. ->d_revalidate() and
->lookup() do *not* take struct nameidata anymore; just the flags.
--
[mandatory]
->create() doesn't take struct nameidata *; unlike the previous
two, it gets "is it an O_EXCL or equivalent?" boolean argument. Note that
local filesystems can ignore tha argument - they are guaranteed that the
object doesn't exist. It's remote/distributed ones that might care...

atomic_open: called on the last component of an open. Using this optional
method the filesystem can look up, possibly create and open the file in
one atomic operation. If it cannot perform this (e.g. the file type
turned out to be wrong) it may signal this by returning 1 instead of
usual 0 or -ve . This method is only called if the last component is
negative or needs lookup. Cached positive dentries are still handled by
f_op->open(). If the file was created, the FILE_CREATED flag should be
set in "opened". In case of O_EXCL the method must only succeed if the
file didn't exist and hence FILE_CREATED shall always be set on success.
tmpfile: called in the end of O_TMPFILE open(). Optional, equivalent to
atomically creating, opening and unlinking a file in given directory.

==============================================================
protected_hardlinks:
A long-standing class of security issues is the hardlink-based
time-of-check-time-of-use race, most commonly seen in world-writable
directories like /tmp. The common method of exploitation of this flaw
is to cross privilege boundaries when following a given hardlink (i.e. a
root process follows a hardlink created by another user). Additionally,
on systems without separated partitions, this stops unauthorized users
from "pinning" vulnerable setuid/setgid files against being upgraded by
the administrator, or linking to special files.
When set to "0", hardlink creation behavior is unrestricted.
When set to "1" hardlinks cannot be created by users if they do not
already own the source file, or do not have read/write access to it.
This protection is based on the restrictions in Openwall and grsecurity.
==============================================================
protected_symlinks:
A long-standing class of security issues is the symlink-based
time-of-check-time-of-use race, most commonly seen in world-writable
directories like /tmp. The common method of exploitation of this flaw
is to cross privilege boundaries when following a given symlink (i.e. a
root process follows a symlink belonging to another user). For a likely
incomplete list of hundreds of examples across the years, please see:
http://cve.mitre.org/cgi-bin/cvekey.cgi?keyword=/tmp
When set to "0", symlink following behavior is unrestricted.
When set to "1" symlinks are permitted to be followed only when outside
a sticky world-writable directory, or when the uid of the symlink and
follower match, or when the directory owner matches the symlink's owner.
This protection is based on the restrictions in Openwall and grsecurity.
==============================================================
suid_dumpable:
This value can be used to query and set the core dump mode for setuid
