Subject: [LTP] pidns31: fix EACCESS error in mq_open()
Date: Wed, 4 Aug 2010 16:52:06 -0700	[thread overview]
Message-ID: <20100804235206.GA1388@us.ibm.com> (raw)


pidns31: mq_open() fails with EACCESS.

pidns31 test case fails with EACCESS - due to the leading '/' in
mqname. See comments in the patch below for details.
