Subject: [PATCH 0/1] userfaultfd: selftest -EEXIST update
Date: Wed, 4 Oct 2017 19:15:40 +0200 [thread overview]
Message-ID: <20171004171541.1495-1-aarcange@redhat.com> (raw)
Hello,
I was stress testing some backports and with high load, after some
time, the latest version of the selftest showed some false positive in
connection with the uffdio_copy_retry. This seems to fix it while
still exercising -EEXIST in the background transfer once in a while.
