Subject: mdopen: only use 'dev' as chosen name if it is a full path.
X-Git-Tag: mdadm-3.0.3~5
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=5ac6db12f9f970f26b7017517789bac200631b11;p=thirdparty%2Fmdadm.git

mdopen: only use 'dev' as chosen name if it is a full path.

Otherwise using names like "r0" causes problem.  They are
handled sufficiently by other paths in the code.
