Reimplement inotify_user using fsnotify. This should be feature for feature
exactly the same as the original inotify_user. This does not make any changes
to the in kernel inotify feature used by audit. Those patches (and the eventual
removal of in kernel inotify) will come after the new inotify_user proves to be
working correctly.Signed-off-by: Eric Paris

The STRIP_ASM_SYMS kconfig symbol mucks up the embedded menu because
STRIP_ASM_SYMS is in the middle of the embedded menu items but it does not
depend on EMBEDDED. Move it to beyond the end of the embedded menu so
that the menu is presented correctly.Or if STRIP_ASM_SYMS should depend on EMBEDDED, that can also be fixed.

Make it possible for the linker to discard local symbols from vmlinux as
they cause vmlinux to balloon when CONFIG_KALLSYMS=y and they cause
dump_stack() and get_wchan() to produce useless information under some
circumstances.With this we add a config option (CONFIG_STRIP_ASM_SYMS) that will cause
the build to supply -X to the linker to tell it to strip temporary local
symbols.This doesn't seem to cause gdb any problems.

Move mqueue vfsmount plus a few tunables into the ipc_namespace struct.
The CONFIG_IPC_NS boolean and the ipc_namespace struct will serve both the
posix message queue namespaces and the SYSV ipc namespaces.The sysctl code will be fixed separately in patch 3. After just this
patch, making a change to posix mqueue tunables always changes the values

Impact: switch default config from CLASSIC_RCU to TREE_RCU
Given that I have not gotten any complaints or bug reports on treercu
recently, this patch makes it be the default. There are a number of
other defconfig files that explicitly call out CLASSIC_RCU, but which
have comment headers saying not to edit them. Probably holdovers from
one of the flavors of "make config", but...Signed-off-by: Paul E. McKenney

Create a dynamically sized pool of threads for doing very slow work items, such
as invoking mkdir() or rmdir() - things that may take a long time and may
sleep, holding mutexes/semaphores and hogging a thread, and are thus unsuitable
for workqueues.The number of threads is always at least a settable minimum, but more are
started when there's more work to do, up to a limit. Because of the nature of
the load, it's not suitable for a 1-thread-per-CPU type pool. A system with
one CPU may well want several threads.This is used by FS-Cache to do slow caching operations in the background, such
as looking up, creating or deleting cache objects.Signed-off-by: David Howells

Allow cpusets to be configured/built on non-SMP systems
Currently it's impossible to build cpusets under UML on x86-64, since
cpusets depends on SMP and x86-64 UML doesn't support SMP.There's code in cpusets that doesn't depend on SMP. This patch surrounds
the minimum amount of cpusets code with #ifdef CONFIG_SMP in order to
allow cpusets to build/run on UP systems (for testing purposes under UML).Reviewed-by: Li Zefan

It's pointed out that swap_cgroup's message at swapon() is nonsense.
Because* It can be calculated very easily if all necessary information is
written in Kconfig.* It's not necessary to annoying people at every swapon().
In other view, now, memory usage per swp_entry is reduced to 2bytes from
8bytes(64bit) and I think it's reasonably small.Reported-by: Hugh Dickins

The COMPAT_BRK kconfig symbol does not depend on EMBEDDED, but it is in
the midst of the EMBEDDED menu symbols, so it mucks up the EMBEDDED menu.
Fix by moving it to just after all of the EMBEDDED menu symbols. Also,
ANON_INODES has a similar problem, so move it to just above the EMBEDDED

This reverts commit 155b25bcc28631a5b5230191aa3f56c40dfffa3f, which was
totally wrong - the "embedded" options still exists (very much so) even
on non-embedded platforms.It's just that we don't bother with actually asking about them when
we're not embedded, we just take their default values (which is usually
'y' - the options add features that may not be worth it in a constrained
environment).Noticed-by: Andrew Morton

Sometimes it happens that KConfig dependencies are not handled
like in the following scenario:- config A
bool- config B
bool
depends on A- config C
bool
select BIf one selects C, then it will select B without checking its
dependency to A, if A hasn't been selected elsewhere, it will
result in a build failure.This is what happens on the following build error:
