Subject: [patch 2.6.17-rc1] Reinstate const in next_thread()
Date: Mon, 03 Apr 2006 18:25:21 +1000 [thread overview]
Message-ID: <25335.1144052721@kao2.melbourne.sgi.com> (raw)
Before commit 47e65328a7b1cdfc4e3102e50d60faf94ebba7d3, next_thread()
took a const task_t. Reinstate the const qualifier, getting the next
thread never changes the current thread.
