From c60305b578674eefe333198c7476dba2178a9082 Mon Sep 17 00:00:00 2001 From: Jan Kara Date: Tue, 5 Feb 2013 14:08:57 +0100 Subject: [PATCH] udf: Make s_block_bitmap standard array struct udf_bitmap has array of buffer pointers attached to it. The code unnecessarily used s_block_bitmap as a pointer to the array instead of the standard trick of using 0 length array in the declaration. Change that to make code more readable and actually shrink the structure by one pointer.
