Subject: util: Add ignored error code
X-Git-Tag: v1.5~13
X-Git-Url: https://www.infradead.org/git/?a=commitdiff_plain;h=1c573cde638eba87c2245b178b940f5727477671;p=users%2Fsagi%2Flibnvme.git

When libnvme ignores a connection attempt via the 'application' context
tracking return an unique error code to allow proper filtering on the
caller side.
