Subject: [PATCH] HFSPlus: change kmalloc/memset to kzalloc

From:	Wyatt Banks <wyatt@...ksresearch.com>

Removed kmalloc and memset in favor of kzalloc.

Signed-off-by:	Wyatt Banks <wyatt@...ksresearch.com>

Patched against 2.6.21.3

To explain the HFSPLUS_SB() macro in the removed memset call:

hfsplus_fs.h:#define HFSPLUS_SB(super)  (*(struct hfsplus_sb_info *)(super)->s_fs_info)
