Re: sys_select

Hello,

My kernel module is talking to user application over a socket. I want to
timeout, if for any reason user application is not running. Using sys_select
seemed like a good idea (until this, see below). The other idea I had was to
use timer and send a sigterm to the thread which is sitting on a sock_recvmsg
call. This works, but there is a race condition, get data over recvmsg, before
I remove timer, timer pops up.

What would be a good way, any suggestions ?
