From 647b7e87b56f594daf648f44abfbeeb5eb6a9457 Mon Sep 17 00:00:00 2001 From: Evgeniy Dushistov Date: Sun, 25 Jun 2006 05:47:29 -0700 Subject: [PATCH] ufs: one way to access super block Super block of UFS usually has size >512, because of fragment size may be 512, this cause some problems. Currently, there are two methods to work with ufs super block: 1) split structure which describes ufs super blocks into structures with size <=512 2) use one structure which describes ufs super block, and hope that array of "buffer_head" which holds "super block", has such construction: bh[n]->b_data + bh[n]->b_size == bh[n + 1]->b_data The second variant may cause some problems in the future, and usage of two variants cause unnecessary code duplication. This patch remove the second variant. Also patch contains some CodingStyle fixes.
