From 01159bd2fab0e9e6bc3c35a04ff20000a07fe43e Mon Sep 17 00:00:00 2001 From: Brian Foster Date: Tue, 27 May 2014 09:07:06 +1000 Subject: [PATCH] repair: helpers for finding in-core inode records w/ free inodes Add the findfirst_free_inode_rec() and next_free_ino_rec() helpers to assist scanning the in-core inode records for records with at least one free inode. These will be used to determine what records are included in the free inode btree.
