From ee802f86899341d835c629a4ad9607135f1b71a2 Mon Sep 17 00:00:00 2001 From: Eric Whitney Date: Thu, 30 Apr 2020 14:53:17 -0400 Subject: [PATCH] ext4: remove dead GET_BLOCKS_ZERO code There's no call to ext4_map_blocks() in the current ext4 code with a flags argument that combines EXT4_GET_BLOCKS_CONVERT and EXT4_GET_BLOCKS_ZERO. Remove the code that corresponds to this case from ext4_ext_handle_unwritten_extents().
