From ece4ceaf2eba1c0da9d6b62bc59a43be6b456548 Mon Sep 17 00:00:00 2001 From: Davidlohr Bueso Date: Mon, 7 Sep 2020 13:32:06 -0700 Subject: kdb: Use newer api for tasklist scanning This kills using the do_each_thread/while_each_thread combo to iterate all threads and uses for_each_process_thread() instead, maintaining semantics. while_each_thread() is ultimately racy and deprecated; although in this particular case there is no concurrency so it doesn't matter. Still lets trivially get rid of two more users.
