William Allen Simpson fb0bbb92d4 Documentation: rw_lock lessons learned
In recent months, two different network projects erroneously
strayed down the rw_lock path.  Update the Documentation
based upon comments by Eric Dumazet and Paul E. McKenney in
those threads.

Further updates await somebody else with more expertise.

Changes:
  - Merged with extensive content by Stephen Hemminger.
  - Fix one of the comments by Linus Torvalds.

Mark Fasheh 14dadf1d5e Add additional examples in Documentation/spinlocks.txt
Checkpatch will throw an error if code doesn't use the correct initializers
for static spinlocks:

ERROR: Use of SPIN_LOCK_UNLOCKED is deprecated: see Documentation/spinlocks.txt

This is fine, but Documentation/spinlocks.txt isn't very clear on how to
_use_ the new initializers for static variables. To save people time in the
future, I added two small examples of how to fix old-style static
initializers to be more lockdep friendly.

Ed L. Cashin 017f021c7e docs: static initialization of spinlocks is OK
Static initialization of spinlocks is preferable to dynamic initialization
when it is practical.  This patch updates documentation for consistency
with comments in spinlock_types.h.

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!
