Subject: kernel/relay.c: a strange usage of delayed_work
Date: Fri, 4 May 2007 01:38:35 +0400 [thread overview]
Message-ID: <20070503213835.GA243@tv-sign.ru> (raw)
In-Reply-To: <20070427184258.62794053.akpm@linux-foundation.org>
relay_switch_subbuf() does schedule_delayed_work(&buf->wake_readers, 1),
wakeup_readers() only does wake_up_interruptible() and nothing more.
Why can't we use a plain timer for this?
In any case, this "wake_up ->read_wait after a minimal possible delay"
looks somewhat strange to me, could you explain? just curious.
Oleg.
