Subject: Remove outdated comment about suspending new tracees
X-Git-Tag: v4.8~228
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=c59b3f13fbc50712785cc2635ab12e8152c96aa1;p=strace

Remove outdated comment about suspending new tracees

We no longer track parent/child relationship between tracees.
Therefore, we no longer suspend new tracee until parent is seen
exiting form [v]fork/clone. The comment is obsolete.

* strace.c (trace): Remove outdated comment.
