From 6d49ba1b47b9c6822d08f90af6f1a2d8ca1cf533 Mon Sep 17 00:00:00 2001 From: Eric Sandeen Date: Mon, 22 Apr 2013 16:12:31 +0000 Subject: btrfs: move leak debug code to functions Clean up the leak debugging in extent_io.c by moving the debug code into functions. This also removes the list_heads used for debugging from the extent_buffer and extent_state structures when debug is not enabled. Since we need a global debug config to do that last part, implement CONFIG_BTRFS_DEBUG to accommodate. Thanks to Dave Sterba for the Kconfig bit.
