From: Trond Myklebust <Trond.Myklebust@netapp.com>
The type "sector_t" is heavily tied in to the block layer interface as an offset/handle to a block, and is subject to a supposedly block-specific configuration option: CONFIG_LBD. Despite this, it is used in struct kstatfs to save a couple of bytes on the stack whenever we call the filesystems' ->statfs().
One consequence is that networked filesystems may break if CONFIG_LBD is not set, since it is quite common to have multi-TB remote filesystems.
The following patch just converts struct kstatfs to use the standard type u64.
