New Revision: 297527
URL: https://svnweb.freebsd.org/changeset/base/297527
Log:
chdone(): Prevent returning uninitialized scalar value.
If there is an error different from ERESTART, there is some
chance that we may end up accessing an uninitialized value. This
doesn't seem likely/possible but initialize announce_buf[0],
just in case.
