[RFC 0/8] Move locking primitives into kernel/locking/

[Peter Zijlstra <peterz@infradead.org>]

Hi all,

During Kernel Summit Dave mentioned that there wasn't a clear maintainer for
locking bits.

To remedy this Ingo suggested gathering all the various locking primitives and
lockdep into a single place: kernel/locking/.

I would further like to propose a MAINTAINERS entry like:

LOCKING
M:      Ingo Molnar <mingo@redhat.com>
M:      Peter Zijlstra <peterz@infradead.org>
M:	Oleg Nesterov <oleg@redhat.com>
M:	"Paul E. McKenney" <paulmck@linux.vnet.ibm.com>
M:	Linus Torvalds <torvalds@linux-foundation.org>
T:      git git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip.git locking/core
S:      Maintained
F:      kernel/locking/

Because for most 'fun' locking discussions we usually end up with at least
those people anyway :-)

Comments?
