Subject[PATCH 1/2]: ufs: wrong type cast
There are two ugly macros in ufs code:
#define UCPI_UBH ((struct ufs_buffer_head *)ucpi)
#define USPI_UBH ((struct ufs_buffer_head *)uspi)
when uspi looks like
struct {
struct ufs_buffer_head ;
}
and USPI_UBH has some sence,
ucpi looks like
struct {
struct not_ufs_buffer_head;
}

To prevent bugs in future, this patch convert
macros to inline function and fix "ucpi" structure.
