[GFS2] Macros removal in gfs2.h
As suggested by Pekka Enberg <penberg@cs.helsinki.fi>. The DIV_RU macro is renamed DIV_ROUND_UP and and moved to kernel.h The other macros are gone from gfs2.h as (although not requested by Pekka Enberg) are a number of included header file which are now included individually. The inode number comparison function is now an inline function. The DT2IF and IF2DT may be addressed in a future patch. Signed-off-by: Steven Whitehouse <swhiteho@redhat.com>
