Christoph Lameter 89ada67917 [PATCH] Use alloc_percpu to allocate workqueues locally
This patch makes the workqueus use alloc_percpu instead of an array.  The
workqueues are placed on nodes local to each processor.

The workqueue structure can grow to a significant size on a system with
lots of processors if this patch is not applied.  64 bit architectures with
all debugging features enabled and configured for 512 processors will not
be able to boot without this patch.

Pekka J Enberg dd3927105b [PATCH] introduce and use kzalloc
This patch introduces a kzalloc wrapper and converts kernel/ to use it.  It
saves a little program text.

Mika Kukkonen 230649da7c [PATCH] create_workqueue_thread() signedness fix
With "-W -Wno-unused -Wno-sign-compare" I get the following compile warning:

  CC      kernel/workqueue.o
kernel/workqueue.c: In function `workqueue_cpu_callback':
kernel/workqueue.c:504: warning: ordered comparison of pointer with integer zero

On error create_workqueue_thread() returns NULL, not negative pointer, so
following trivial patch suggests itself.

James Bottomley 6068674437 [PATCH] remove name length check in a workqueue
We have a chek in there to make sure that the name won't overflow
task_struct.comm[], but it's triggering for scsi with lots of HBAs, only
scsi is using single-threaded workqueues which don't append the "/%d"
anyway.

All too hard.  Just kill the BUG_ON.

[ kthread_create() uses vsnprintf() and limits the thing, so no
  actual overflow can actually happen regardless ]

James Bottomley 81ddef77bb [PATCH] re-export cancel_rearming_delayed_workqueue
This was unexported by Arjan because we have no current users.

However, during a conversion from tasklets to workqueues of the parisc led
functions, we ran across a case where this was needed.  In particular, the
open coded equivalent of cancel_rearming_delayed_workqueue was implemented
incorrectly, which is, I think, all the evidence necessary that this is a
useful API.

Linus Torvalds 1da177e4c3 Linux-2.6.12-rc2
Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.

Let it rip!
