From ff6ae7ce34fe2edc78be7d7d1997b25a700b5f80 Mon Sep 17 00:00:00 2001 From: =?utf8?q?Rafa=C5=82=20Mi=C5=82ecki?= Date: Thu, 24 Sep 2015 11:19:12 +0000 Subject: [PATCH] kernel: remove old "rootfs" splitter MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit A year ago I made this old splitter obsolete (see r42828), it's time to completely remove it now. For all this time we got these warnings: "Dedicated partitioner didn't create "rootfs_data" partition, please fill a bug report!" and "Support for built-in "rootfs_data" splitter will be removed, please use CONFIG_MTD_SPLIT_SQUASHFS_ROOT" but I'm not aware of any bug reports related to that.
