-Subject: [PATCH] leds: convert IDE trigger to common disk trigger
-MIME-Version: 1.0
-Content-Type: text/plain; charset=UTF-8
-Content-Transfer-Encoding: 8bit
-
-This patch converts the IDE specific LED trigger to a generic disk
-activity LED trigger. The libata core is now a trigger source just
-like before the IDE disk driver. It's merely a replacement of the
-string ide by disk.
-
-The patch is taken from http://dev.gentoo.org/~josejx/ata.patch and is
-widely used by any ibook/powerbook owners with great satisfaction.
-Likewise, it is very often used successfully on different ARM platforms.
-
-Unlike the original patch, the existing 'ide-disk' trigger is still
-available for backward compatibility. That reduce the amount of patches
-in affected device trees out of the mainline kernel. For further
-development, the new name 'disk-activity' should be used.
