ida: make ida_simple_get/put() IRQ safe

2011-11-02T23:07:00+00:00

It's often convenient to be able to release resource from IRQ context.
Make ida_simple_*() use irqsave/restore spin ops so that they are IRQ
safe.

ida: simplified functions for id allocation

2011-08-04T00:25:20+00:00

The current hyper-optimized functions are overkill if you simply want to
allocate an id for a device.  Create versions which use an internal
lock.

In followup patches, numerous drivers are converted to use this
interface.

Thanks to Tejun for feedback.

idr: fix idr_pre_get() locking description

2010-10-26T23:52:18+00:00

Despite the idr_pre_get() kernel-doc, there are some cases where you can
call idr_pre_get() from within locked regions.  Add a description for such
cases.
