Date: Wed, 2 Jul 2008 12:08:33 -0500 From: Nathan Lynch <ntl@...ox.com> To: Andrew Morton <akpm@...ux-foundation.org> Cc: Paul Mackerras <paulus@...ba.org>, torvalds@...ux-foundation.org, linux-kernel@...r.kernel.org, greg@...ah.com Subject: [PATCH] sysfs-rules.txt: reword API stability statement The first paragraph of this document implies that user space developers shouldn't use sysfs at all, but then it goes on to describe rules that developers should follow when accessing sysfs. Not only is this somewhat self-contradictory, it has been shown to discourage developers from using established sysfs interfaces. A note of caution is more appropriate than a blanket "sysfs will never be stable" assertion.
