New Revision: 253631
URL: http://svnweb.freebsd.org/changeset/base/253631
Log:
MFC r253476:
Add message when nvd disks are attached and detached.
As part of this commit, add an nvme_strvis() function which borrows
heavily from cam_strvis(). This will allow stripping of
leading/trailing whitespace and also handle unprintable characters
in model/serial numbers. This function goes into a new nvme_util.c
file which is used by both the driver and nvmecontrol.
