Author: gleb Date: Fri May 18 10:01:31 2012 New Revision: 235601 URL: http://svn.freebsd.org/changeset/base/235601 Log: Don't use ino_t in dumprestore protocol definition. Since ino_t size is about to change to 64-bits, replace ino_t used in dump protocol definition with 32-bit dump_ino_t to preserve backward compatibility. At some point, it may be necessary to use spare fields in struct in order to fully support 64-bit inode numbers.
