[libvirt] [PATCH v2 0/3] Be more selective when determining cdrom for taint messaging

v1: https://www.redhat.com/archives/libvir-list/2017-September/msg00103.html Changes since v1: Split into 3 parts... The first patch would be the bare minimum using STRPREFIX instead of STREQ type comparisons for the incoming path to be "/dev/cdrom[N]" or "/dev/srN" (or resolved to that). This would "work" for the most part, but then since it's possible to make even more checks let's check against the collected node device data. Patch 2 therefore will "tag" the already collected cdrom data with a capability. This allows patch3 to find any/all CDROM's on the host and compare the resolved path to that list of devices returning "true" if something matches a node device declared physical CDROM. I split things up mainly to make it easier to decide whether patch 1 is sufficient or not. If patch2 and patch3 are OK, I would also add a release note indicating the improvement to find CDROM by node device capability. It's a separate "improvement" on it's own as well. Whether it's truly useful or not, is a different question...
