Re: locking against myself in unionfs code

Thanks for the fast analysis!

I doubt another process was doing anything on that file system.

What I was running was a borg extract on a work dir which had union-mounted 
below (mount_union -b) a borg extract-ion of an older archive. I doubt borg 
does anything multi-threaded and I wasn't running anything else on that 
development server at that time.
