From 3c3aa5dbd65915abaa87d91330f4463c99d0df44 Mon Sep 17 00:00:00 2001 From: Oded Gabbay Date: Wed, 23 Sep 2020 23:51:03 +0300 Subject: habanalabs: add debug messages for opening/closing context During debugging of error we sometimes need to know whether the error happened when a user context was open. Add debug prints when opening and closing user contexts.
