[LU-11719] Refactor search_itree

• Type: Bug
• Resolution: Fixed
• Priority: Minor
• Fix Version/s: Lustre 2.13.0, Lustre 2.12.6
• Labels: patch
• Severity: 3
• Assignee: Patrick Farrell (Inactive)
• Reporter: Patrick Farrell (Inactive)

Description

The behavior of search_itree is different from its close relative search_queue in ways that are a little confusing.  Also, in some cases, it will continue searching the trees after a lock has been found.

This is a low priority bug to slightly refactor its behavior, inspired because the difference between search_itree and search_queue introduced a subtle bug in the LU-11670 patch.
