From 574ca174c97f790086e3e6f2251381420ad38fd0 Mon Sep 17 00:00:00 2001 From: Theodore Ts'o Date: Fri, 11 Jul 2008 19:27:31 -0400 Subject: [PATCH] ext4: Rename read_block_bitmap() to ext4_read_block_bitmap() Since this a non-static function, make it be ext4 specific to avoid conflicts with potentially other filesystems.
