Subject: [PATCH] Minor __sched cleanups
Date: Wed, 14 Apr 2004 11:38:06 +1000	[thread overview]
Message-ID: <1081906686.22908.31.camel@bach> (raw)

Fairly minor cleanups to wli's recent __sched implementation:

Name: Minor __sched Cleanups
Status: Tested on 2.6.5-mm4
Version: -mm

1) __sched_text_start and __sched_test_end are more normal section
   marker names, and can be used directly.

2) There is no comment and no reason for __sched to be in linux/init.h:
   linux/sched.h would be preferable.
