Subject: runtime: remove unused mutexevent linkname
X-Git-Url: http://www.git.cypherpunks.su/?a=commitdiff_plain;h=84c8483e02280a87d71eac6b231a514200dfab2b;p=gostls13.git

runtime: remove unused mutexevent linkname

CL 29650 added a sync.event linkname for mutexevent, but that does not
appear to have ever been used. This linkname isn't in the "hall of
shame", so we can just remove it.
