Author: eugen Date: Sat Oct 27 16:14:42 2018 New Revision: 339815 URL: https://svnweb.freebsd.org/changeset/base/339815
Log: Extend stripeoffset and stripesize of GEOMs from u_int to off_t GEOM's stripeoffset overflows at 4 gigabyte margin (2^32) because of its u_int type. This leads to incorrect data in the output generated by "sysctl kern.geom.confxml" command, "graid list" etc. when GEOM array has volumes larger than 4G, for example. This change does not affect ABI but changes KBI. No MFC planned.
