Subject: [PATCH] preempt abstraction
Date: Tue, 08 Jan 2002 17:40:19 +0000	[thread overview]
Message-ID: <10940.1010511619@warthog.cambridge.redhat.com> (raw)


The following patch abstracts access to need_resched:

	ftp://infradead.org/pub/people/dwh/preempt-252p10.diff.bz2

It replaces most C-source read accesses to it with need_preempt() which
returns true if rescheduling is necessary.

It also replaces instances of:

	if (current->need_resched())
		schedule();

With:

	preempt();

It doesn't (or at least shouldn't) do anything else.

Cheers,
David
