New Revision: 230064
URL: http://svn.freebsd.org/changeset/base/230064
Log:
Allow an MBR primary or extended Linux swap partition to be specified
as the system dump device. This was already allowed for GPT. The Linux
swap metadata at the beginning of the partition should not be disturbed
because the crash dump is written at the end.
