Subject: When the client tries to __NR_close() our logfile, claim the close
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=39e41c534017c7349971dedf554df738eac71218;p=thirdparty%2Fvalgrind.git

When the client tries to __NR_close() our logfile, claim the close
succeeded, which is a lie since we just ignore it -- otherwise the
log disappears at that point.
