New Revision: 345032
URL: https://svnweb.freebsd.org/changeset/base/345032
Log:
Augment the UFS filesystem specific print function (called by the
kernel vn_printf() routine when printing out vnodes associated with
a UFS filesystem) to also include the inode's link count, effective
link count, generation number, owner, group, flags, size, and for
UFS2 filesystems, the extent size.
