From b026ce1ee92de325463535c15ab5575f21b23702 Mon Sep 17 00:00:00 2001 From: Carlos O'Donell Date: Mon, 11 Feb 2019 16:02:56 -0500 Subject: nptl: Fix pthread_tryjoin comment. In pthread_tryjoin if pd->tid == 0 then we will not block on a futex operation because we will immediately see the join is already complete and return. The comment is fixed to reflect that.
