Subject: Suppress unimplemented fcntl command warning with -q
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=aec4871f7c9deed31f5d5606e4f9d07b43a448ec;p=thirdparty%2Fvalgrind.git

Suppress unimplemented fcntl command warning with -q

LTP tests fcntl13 and fcntl13_64 fail because even with -q valgrind
emits warnings about unknown (999) fcntl commands. Don't emit that
message with -q, just fail with EINVAL.
