From 75ac2dd907013b44edbdec16f8969d14811149c9 Mon Sep 17 00:00:00 2001 From: Kelley Nielsen Date: Mon, 4 Nov 2013 19:35:58 -0800 Subject: btrfs: expand btrfs_find_item() to include find_root_ref functionality This patch is the second step in bootstrapping the btrfs_find_item interface. The btrfs_find_root_ref() is similar to the former __inode_info(); it accepts four of its parameters, and duplicates the first half of its functionality. Replace the one former call to btrfs_find_root_ref() with a call to btrfs_find_item(), along with the defined key type that was used internally by btrfs_find_root ref, and a null found key. In btrfs_find_item(), add a test for the null key at the place where the functionality of btrfs_find_root_ref() ends; btrfs_find_item() then returns if the test passes. Finally, remove btrfs_find_root_ref().
