• 4dfbb9d8c   Lockdep: add lockdep_set_class_and_subclass() and lockdep_set_subclass() ... Browse Code »

  This annotation makes it possible to assign a subclass on lock init. This
  annotation is meant to reduce the _nested() annotations by assigning a
  default subclass.

  One could do without this annotation and rely on lockdep_set_class()
  exclusively, but that would require a manual stack of struct lock_class_key
  objects.

• fdf8cb090   [PATCH] lib/rwsem.c: un-inline rwsem_down_failed_common() ... Browse Code »

  Un-inlining rwsem_down_failed_common() (two callsites) reduced lib/rwsem.o
  on my Athlon, gcc 4.1.2 from 5935 to 5480 Bytes (455 Bytes saved).

  I thus guess that reduced icache footprint (and better function caching) is
  worth more than any function call overhead.

  Replace a number of memory barriers with smp_ variants. This means we won't
  take the unnecessary hit on UP machines.

  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!
