From dd73a01a30d729e8fa6f829c4582650e258e36f9 Mon Sep 17 00:00:00 2001 From: Christoph Hellwig Date: Fri, 1 Oct 2010 05:42:59 +0200 Subject: hfsplus: fix HFSPLUS_SB calling convention HFSPLUS_SB doesn't return a pointer to the hfsplus-specific superblock information like all other FOO_SB macros, but dereference the pointer in a way that made it look like a direct struct derefence. This only works as long as the HFSPLUS_SB macro is used directly and prevents us from keepig a local hfsplus_sb_info pointer. Fix the calling convention and introduce a local sbi variable in all functions that use it constantly.
