control: use reference-counted pid

2009-11-06T13:32:06+00:00

Instead of storing the PID number, take a reference to the task's pid
structure.  This protects against duplicates due to PID overflows, and
using pid_vnr() ensures that the PID returned by snd_ctl_elem_info() is
correct as seen from the current namespace.

control: remove snd_konctrol_volatile::owner_pid field

2009-11-06T13:32:03+00:00

We do not need to save the ID of the process that locked a control
because that information is already available in the owner's file data.

ALSA: add snd_ctl_add_slave_uncached()

2009-03-09T13:56:19+00:00

Added snd_ctl_add_slave_uncached() function to add a slave element
with volatile controls.  The values of normal slave elements are
supposed to be cachable, i.e. they are changed only via the put
callbacks.  OTOH, when a slave element is volatile and its values may
be changed by other reason (e.g. hardware status change), the values
will get inconsistent.

The new function allows the slave elements with volatile changes.
When the slave is tied with this call, the native get callback is
issued at each time so that the values are always updated.

Now that everyone uses snd_ctl_new1() and noone is using snd_ctl_new()
anymore, we can make it static.
