[PATCH] 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.
