From 3613d22807a2616e9346800bacd88aa8bbbefcd7 Mon Sep 17 00:00:00 2001 From: Jan Kara Date: Tue, 4 Jun 2013 13:19:34 -0400 Subject: ext4: remove buffer_uninit handling There isn't any need for setting BH_Uninit on buffers anymore. It was only used to signal we need to mark io_end as needing extent conversion in add_bh_to_extent() but now we can mark the io_end directly when mapping extent.
