From 9695ef16ed4e00b59303f39f9a4a422a2c6a3b89 Mon Sep 17 00:00:00 2001 From: Evgeniy Dushistov Date: Sun, 25 Jun 2006 05:47:22 -0700 Subject: [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.
