Subject: Re: [PATCH v2 0/3] leds: blink resolution improvements

Hi Stas,

Have you tested it? I tried it with Samsung M0 board and
my leds-aat1290 driver. It didn't work well. And for small delay
intervals it will not have a chance to work reliably with all drivers,
especially the ones which use mutex in their brightness_set op,
since mutex can sleep.

I am afraid that we have to stay with what we have currently.
