ext4: each filesystem creates and uses its own mb_cache
This patch adds new interfaces to create and destory cache, ext4_xattr_create_cache() and ext4_xattr_destroy_cache(), and remove the cache creation and destory calls from ex4_init_xattr() and ext4_exitxattr() in fs/ext4/xattr.c. fs/ext4/super.c has been changed so that when a filesystem is mounted a cache is allocated and attched to its ext4_sb_info structure. fs/mbcache.c has been changed so that only one slab allocator is allocated and used by all mbcache structures.
