Subject: [KJ] [PATCH 7/22] ftape/fdc-io: insert set_current_state() before
Date: Mon, 17 Jan 2005 21:20:11 +0000	[thread overview]
Message-ID: <20050117212011.GI24698@us.ibm.com> (raw)

Hi,

Please consider applying.

Description: Inserts a set_current_state(TASK_INTERRUPTIBLE) before the
schedule_timeout() call. Without this change, after the first iteration of the
loop, schedule_timeout() will not only return immediately, but the loop will
break, as the conditional will no longer be satisfied. In fact, this conditional
makes little sense given the workings of schedule_timeout. The timeout variable
is ignored, as well, and I'm fairly certain that it should be included in the
loop conditional. That way, if the timeout expires before a signal hits, -ETIME
will be returned by fdc_interrupt_wait() instead of -EINTR.
