Author: cem Date: Thu Aug 9 21:53:32 2018 New Revision: 337554 URL: https://svnweb.freebsd.org/changeset/base/337554 Log: cam(4): Add an xpt-neutral flag indicating a valid panic CCB No functional change. Note that this change is careful to set the CCB header xflags after foo_fill_bar() routines, which generally zero existing flags. An earlier version of this patch mistakenly set the flag before the fill routines.
