Author: mav Date: Thu Dec 29 15:09:34 2016 New Revision: 310778 URL: https://svnweb.freebsd.org/changeset/base/310778 Log: Improve use of I/O's private area. - Since I/Os are allocates from per-port pools, make allocations store pointer to CTL softc there, and use it where needed instead of global. - Created bunch of helper macros to access LUN, port and CTL softc.
