Subject: Add support for the SIOCGPGRP ioctl and mark SIOCSPGRP as non-blocking
X-Git-Tag: svn/VALGRIND_3_0_0~1588
X-Git-Url: http://git.ipfire.org/gitweb.cgi?a=commitdiff_plain;h=8adabd32535f255fe1904b5ceeb7d99725f586e5;p=thirdparty%2Fvalgrind.git

Add support for the SIOCGPGRP ioctl and mark SIOCSPGRP as non-blocking
to avoid older kernels returning EPERM due to it being run in a separate
thread. This fixes bug #89198.
