The devices specification consists of multiple rules separated by spaces. The rules have a syntax of shell-style wildcards and are either positive or negative. The negative rules are prefixed with an exclamation mark. c C s t | t � r$ t j d | � } n g | D]/ } | j d � r+ | j � d k r+ | ^ q+ } g | D] } | | k rg | d ^ qg } t | � d k r� | j d � n t } x* | D]" } t j | | � r� t } Pq� q� Wx* | D]" } t j | | � r� t } Pq� q� W| S( s Match a device against the specification in the profile. If there is no positive rule in the specification, implicit rule which matches all devices is added. The device matches if and only if it matches some positive rule, but no negative rule. s \s|,\s*t !t i i t *( t isinstancet strt ret splitt startswitht stript lent appendt Falset fnmatcht True( t selft rulest device_namet rulet positive_rulest negative_rulest matches( ( sA /usr/lib/python2.7/site-packages/tuned/hardware/device_matcher.pyt match s <) c C s= g } x0 | D]( } | j | | � r | j | � q q W| S( s� Match a device list against the specification in the profile.
