From bcd6d4ecf6868ed57d4daae5d48e52d0752566d2 Mon Sep 17 00:00:00 2001 From: Christoph Hellwig Date: Tue, 16 Oct 2007 23:26:51 -0700 Subject: ufs: move non-layout parts of ufs_fs.h to fs/ufs/ Move prototypes and in-core structures to fs/ufs/ similar to what most other filesystems already do. I made little modifications: move also ufs debug macros and mount options constants into fs/ufs/ufs.h, this stuff also private for ufs.
