This fourth version of HST applies the suggestion from Mikulas Patocka to do the ktime_get_ns inside the mpath map_bio instead of generic device-mapper code. This means that struct dm_mpath_io gained another 64bit field. For the request-based case, we continue to use the block layer start time information.
You should add some info to the multipath.conf.5 man page ( https://git.opensvc.com/gitweb.cgi?p=multipath-tools/.git;a=blob;f=multipath/multipath.conf.5;h=05a5e8ffeb110d969f3b2381eb3b88d7f28380f6;hb=HEAD#l189 ),
