New Revision: 277363
URL: https://svnweb.freebsd.org/changeset/base/277363
Log:
MFC r277044:
Increase the maximum number of dynamic USB quirks. USB memory stick
devices which don't support the synchronize cache SCSI command are
likely to also not support the prevent-allow medium removal SCSI
command.
