Dave, This is a batch of (mostly) fixes instended for 2.6.31. Most of them are fixes, many with references to bug reports. Most of the rest is fall-out and stragglers related to the rfkill rework. There is also the addition of a debugfs file to aid debugging. Please let me know if there are problems! Thanks, John --- Individual patches are available here: http://www.kernel.org/pub/linux/kernel/people/linville/wireless-next-2.6/ --- The following changes since commit 9cbc1cb8cd46ce1f7645b9de249b2ce8460129bb: David S.
