From 470173274d9ceb18a7140ef93e20be6c2236e7d9 Mon Sep 17 00:00:00 2001 From: Ionut Nicu Date: Mon, 13 Jan 2014 11:59:24 +0100 Subject: ext4fs: use EXT2_BLOCK_SIZE instead of fs->blksz Using fs->blksz in ext4fs_get_extent_block() is not correct since fs->blksz is not initialized on the read path. Use EXT2_BLOCK_SIZE() instead which will produce the desired output.
