Since we could not get the generic API accepted, can I send out V2
which would use container_of()?

I could not get the generic API accepted upstream. We would stick to
from_tasklet()
or container_of(). Could I go ahead and send out V2 using
from_tasklet() with subject line fixed?
Thanks,

Yes, there is a new macro by name cast_out() is suggested in place of
from_tasklet(). Hopefully it will go in soon. Will spin out V2 with the change
and also re-word subject l
e to adapt to this new API.

Hi All,
Under heavy stress and constant memory hot add/remove, I have observed
the following loop to occasionally loop infinitely:

This patch introduces a mutex that prevents any subsequent PRRN events from
running while there is a prrn event being handled, allowing rtas polling to
continue normally.
