Hi!
It also drew my attention to the issue of desired pattern sysfs
interface semantics on uninitialized pattern. In your implementation
user seems to be unable to determine if the pattern is activated
or not. We should define the semantics for this use case and
describe it in the documentation. Possibly pattern could
return alone new line character then.
Let me take a step back: we have triggers.. like LED blinking.
How is that going to interact with patterns? We probably want the
patterns to be ignored in that case...?
Which suggest to me that we should treat patterns as a trigger. I
believe we do something similar with blinking already.
Then it is easy to determine if pattern is active, and pattern
vs. trigger issue is solved automatically.
I'm all for it. I proposed this approach during the previous
discussions related to possible pattern interface implementations,
but you seemed not to be so enthusiastic in [0].
