Subject: [PATCH 2/4] ptrace: remove PT_DTRACE from avr32, mn10300, parisc, s390, sh, xtensa
Date: Thu, 23 Apr 2009 21:32:06 +0200 [thread overview]
Message-ID: <20090423193206.GA14885@redhat.com> (raw)
avr32, mn10300, parisc, s390, sh, xtensa:
they never set PT_DTRACE, but clear it after do_execve().
