[PATCH] paride: register_chrdev fix · 8637980b

由 Andrew Morton 提交于 3月 28, 2006

If the user specified `major=0' (odd thing to do), pg.c will use dynamic
allocation. We need to pick up that major for subsequent unregister_chrdev().

[PATCH] let BLK_DEV_RAM_COUNT depend on BLK_DEV_RAM · a687fb18

由 Adrian Bunk 提交于 3月 28, 2006

It's purely cosmetic, but with the patch there's no longer a
BLK_DEV_RAM_COUNT setting in the .config if BLK_DEV_RAM=n.

[PATCH] synclink_gt: remove uneeded async code · be4676e6

由 Paul Fulghum 提交于 3月 28, 2006

Remove code in async receive handling that serves no purpose with new tty
receive buffering.  Previously this code tried to free up receive buffer
space, but now does nothing useful while making expensive calls.

[PATCH] synclink: remove dead code · 86a34147

由 Paul Fulghum 提交于 3月 28, 2006

Remove dead code from synclink driver.  This was used previously when the
write method had a from_user flag, which has been removed.

[PATCH] Decrapify asm-generic/local.h · f5f5370d

由 Kyle McMartin 提交于 3月 28, 2006

Now that Christoph Lameter's atomic_long_t support is merged in mainline,
might as well convert asm-generic/local.h to use it, so the same code can
be used for both sizes of 32 and 64-bit unsigned longs.

akpm sayeth:

Q:

  Is there any particular reason why these routines weren't simply
  implemented with local_save/restore_flags, if they are only meant to
  guarantee atomicity to the local cpu?  I'm sure on most platforms this
  would be more efficient than using an atomic...

A:

  The whole _point_ of local_t is to avoid local_irq_disable().  It's
  designed to exploit the fact that many CPUs can do incs and decs in a way
  which is atomic wrt local interrupts, but not atomic wrt SMP.

But this patch makes sense, because asm-generic/local.h is just a fallback
implementation for architectures which either cannot perform these
local-irq-atomic operations, or its maintainers haven't yet got around to
implementing them.

We need more work done on local_t in the 2.6.17 timeframe - they're defined as
unsigned long, but some architectures implement them as signed long.
