From 9b8f1f0106ab39ad58765d4e7c57189835f51127 Mon Sep 17 00:00:00 2001 From: Mingming Cao Date: Wed, 11 Oct 2006 01:21:13 -0700 Subject: [PATCH] ext4: removesector_t bits check Previously when in-kernel ext4 block type is sector_t, it's only 4 bits long under some 32bit arch (when CONFIG_LBD is not on). So we need to check the size of sector_t before we read 48bit long on-disk blocks to in-kernel blocks. These checks are unnecessary now as we changed the in-kernel blocks to unsigned longlong.
