From 86028619b9f653a30f5aa0d331fdedd899a1eea5 Mon Sep 17 00:00:00 2001 From: Bart Van Assche Date: Tue, 16 Aug 2011 18:42:22 +0200 Subject: docs/sysfs: Specify ABI documentation requirements Although it is expected nowadays that every new sysfs attribute is documented under Documentation/ABI, this is not yet mentioned in the kernel documentation. This patch adds a note in the sysfs documentation about that requirement.
