From 945b092011c6af71a0107be96e119c8c08776f3f Mon Sep 17 00:00:00 2001 From: Colin Leroy Date: Sun, 1 May 2005 08:59:16 -0700 Subject: [PATCH] hfs, hfsplus: don't leak s_fs_info and fix an oops This patch fixes the leak of sb->s_fs_info in both the HFS and HFS+ modules. In addition to this, it fixes an oops happening when trying to mount a non-hfsplus filesystem using hfsplus. This patch is from Roman Zippel, based off patches sent by myself.
