Subject: nptl: Fix pthread_tryjoin comment.
X-Git-Tag: upstream/2.30~338
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=b026ce1ee92de325463535c15ab5575f21b23702;p=external%2Fglibc.git

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.
