1.) The first patch adds a feature flags bit field to the multipath
structure for selected features.
2.) The second patch allows a user to set a feature flag for a dm-mpath
device of "no_abort_q" to indicate that deactivate_path should not call
blk_abort_queue. I tried to select a short feature name to feature output
listed with multipath -l would not be too long "features='2 queue_if_no_path
no_abort_q'
