Hi Timur, I have said this before: in the first timeout, just panic() maybe not enough, in [RFC] version of my patchset, I offer some option as "preaction" to use, but for simplifying the first version of driver, I have deleted them. but at least, panic() is far more useful than a simple reset. at least, it can provide the context of the crashed system to admin. If you want to warn user space, that will make driver more complicated, I don't think that is a good choose for a first version. but we can find a way to improve this later On 24 May 2015 at 23:02, Timur Tabi <timur@xxxxxxxxxxxxxx> wrote: > Fu Wei wrote: >> >> If pretimeout concept assumes that there are two timers, I >> misunderstand the "pretimeout", then I will delete the pretimeout >> immediately. > > > In my opinion, calling panic() on a pre-timeout is not useful, because > that's really just a normal timeout.
