New Revision: 209497
URL: http://svn.freebsd.org/changeset/base/209497
Log:
MFC r207094 (by marcel):
Implement the resize verb and add support for resizing partitions
for all schemes but EBR.
MFC r207095 (by marcel):
Implement the resize command for resizing partitions. Without new
size, the partition in question is resized to fill all available
space.
