From 90d0b5eead05174cea371788cc4766bc7739e982 Mon Sep 17 00:00:00 2001 From: David Oberhollenzer Date: Sun, 12 Jan 2020 08:22:28 +0100 Subject: Add a start anchor parameter to sqfs_dir_reader_find_by_path It optionally allows code that does tree traversal to start at an inode that it obtained previously and makes it easier to keep state externally.
