From 01f49d0b9d0209dc1194255b11601e4b94447b36 Mon Sep 17 00:00:00 2001 From: Theodore Ts'o Date: Mon, 10 Jan 2011 12:13:03 -0500 Subject: [PATCH] ext4: use ext4_lblk_t instead of sector_t for logical blocks This fixes a number of places where we used sector_t instead of ext4_lblk_t for logical blocks, which for ext4 are still 32-bit data types. No point wasting space in the ext4_inode_info structure, and requiring 64-bit arithmetic on 32-bit systems, when it isn't necessary.
