From 4ce3b77480496a20cf380bd18a8ae4a414b7d4a0 Mon Sep 17 00:00:00 2001 From: Theodore Ts'o Date: Sat, 1 Sep 2007 09:10:43 -0400 Subject: [PATCH] Don't byte swap extents information in the inode Responsibility for byte swapping the extents information rests with the low-level extent code, which translates the on-disk extents information to the abstract extent format. The on-disk format will eventually get more complicated, in order to add support for 64-bit block numbers, bit-compressed extents, etc. So to avoid needing to expose all of that complexity in swapfs.c, the in-memory contents of i_blocks will not be byte-swapped and will be identical to the on-disk format.
