[LU-6383] Improve LDLM debug on lock matching (search_queue)

• Type: Improvement
• Resolution: Won't Do

Description

The search_queue function is at the core of ldlm_lock matching, and there is currently no debug output from it to track the lock matching process or indicate the reason lock matching failed.

This is extremely useful for debugging certain issues, see, for example, LU-6368.

I'm proposing a patch to add debug in this area. (Patch coming shortly...)

Debug not needed, too extensive for normal use.
