[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.
