Add additional debugging to check that the objects is actually from the cache
the caller claims. Doing so currently trips up some other debugging code. It
takes a lot to infer from that what was happening.

V2: Only warn once.

Move the code to append the new kmem_cache to the list of slab caches to
the kmem_cache_create code in the shared code.

This is possible now since the acquisition of the mutex was moved into
kmem_cache_create().

V1->V2:
	- SLOB: Add code to remove the slab from list
	 (will be removed a couple of patches down when we also move the
	 list_del to common code).

Instead of using s == NULL use an errorcode. This allows much more
detailed diagnostics as to what went wrong. As we add more functionality
from the slab allocators to the common kmem_cache_create() function we will
also add more error conditions.

Print the error code during the panic as well as in a warning if the module
can handle failure. The API for kmem_cache_create() currently does not allow
the returning of an error code. Return NULL but log the cause of the problem
in the syslog.

kmem_cache_destroy does basically the same in all allocators.

Extract common code which is easy since we already have common mutex handling.

V1-V2:
	- Move percpu freeing to later so that we fail cleaner if
		objects are left in the cache [JoonSoo Kim]

Do not use kmalloc() but kmem_cache_alloc() for the allocation
of the kmem_cache structures in slub.

Add additional debugging to check that the objects is actually from the cache
the caller claims. Doing so currently trips up some other debugging code. It
takes a lot to infer from that what was happening.

V2: Only warn once.

The freeing action is basically the same in all slab allocators.
Move to the common kmem_cache_destroy() function.

Simplify locking by moving the slab_add_sysfs after all locks
have been dropped. Eases the upcoming move to provide sysfs
support for all allocators.

Do the initial settings of the fields in common code. This will allow
us to push more processing into common code later and improve readability.

  To: Pekka Enberg; +Cc: Joonsoo Kim, Glauber Costa, linux-mm, David Rientjes

Duping of the slabname has to be done by each slab. Moving this code
to slab_common avoids duplicate implementations.

With this patch we have common string handling for all slab allocators.
Strings passed to kmem_cache_create() are copied internally. Subsystems
can create temporary strings to create slab caches.

Slabs allocated in early states of bootstrap will never be freed (and those
can never be freed since they are essential to slab allocator operations).
During bootstrap we therefore do not have to worry about duping names.

Shift the allocations to common code. That way the allocation
and freeing of the kmem_cache structures is handled by common code.

V2->V3: Use GFP_KERNEL instead of GFP_NOWAIT (JoonSoo Kim).
V1->V2: Use the return code from setup_cpucache() in slab instead of returning -ENOSPC

The code that was fixed is removed in one of the later patches.

I don't see how it matters.

This code is prone to errors, as can be easily seen by the amount of
interactions it had, all of them with bugs. Our best friend in finding
those bugs is pinpointing the patch where it happens. Please make it easy.

Yes this is pretty key stuff and I am definitely trying to make it as
clean and easy possible.. I am trying my best but I have a limited time
that I can spend on running tests.

It would help if you could try to understand the code, suggest
improvements and verify that the changes are sane. So far I mostly see
"this aint working" instead of an engagement with the code.

That is understandable. The way to scale that is to have other people
testing the final result, and that is precisely what I am doing.

You can't be serious...
I tested every series you posted. I code reviewed all your iterations so
far. Found a bunch of bugs, debugged all of them up to v11. Pinpointed
to you the exact source of a lot of them, as a result of the
aforementioned debugging.

How isn't it engagement? Seriously?

Well yes, that debugging and review used to be there in the past but not
in the latest iterations. Bisecting and pointing to the patch does not
require an understanding of the code.

In order to make faster progress it may also be useful to stop at the
patch that is not working for you and ensure that those before are
properly reviewed so that at least those can be merged.

The slab aliasing logic causes some strange contortions in
slub. So add a call to deal with aliases to slab_common.c
but disable it for other slab allocators by providng stubs
that fail to create aliases.

Full general support for aliases will require additional
cleanup passes and more standardization of fields in
kmem_cache.

V1->V2:
	- Move kstrdup before kmem_cache_alias invocation.
	(JoonSoo Kim)

What is done there can be done in __kmem_cache_shutdown.

This affects RCU handling somewhat. On rcu free all slab allocators
do not refer to other management structures than the kmem_cache structure.
Therefore these other structures can be freed before the rcu deferred
free to the page allocator occurs.

Simplify bootstrap by statically allocated two kmem_cache structures. These are
freed after bootup is complete. Allows us to no longer worry about calculations
of sizes of kmem_cache structures during bootstrap.

Simplify setup and reduce code in kmem_cache_init(). This allows us to
get rid of initarray_cache as well as the manual setup code for
the kmem_cache and kmem_cache_node arrays during bootstrap.

We introduce a new bootstrap state "PARTIAL" for slab that signals the
creation of a kmem_cache boot cache.

V1->V2: Get rid of initarray_cache as well.

Extract the code to do object alignment from the allocators.
Do the alignment calculations in slab_common so that the
__kmem_cache_create functions of the allocators do not have
to deal with alignment.

The nodelists field in kmem_cache is pointing to the first unused
object in the array field when bootstrap is complete.

On boot we use a statically allocated array for that purpose.

A problem with the current approach is that the statically sized
kmem_cache structure can only contain NR_CPUS entries. If the number
of nodes plus the number of cpus is greater then we would overwrite
memory following the kmem_cache_boot definition.

Increase the size of the array field to ensure that also the node
pointers fit into the array field.

Once we do that we no longer need the kmem_cache_nodelists
array and we can then also simplify bootstrap.
