Module Name:    src
Committed By:   jdolecek
Date:           Wed Apr  5 18:34:56 UTC 2017

        src/sys/dev: ccd.c
        src/sys/sys: dkio.h

Log Message:
introduce DKCACHE_COMBINE() macro - it combines the flags in a way that
all common flags are retained, and flags regarding write cache are preserved
if either of the devices has it; callers can thus rely on write cache not
being possible to be used when both flags are missing

use the new macro for ccd(4)
