       __break_lease - revoke all outstanding leases on file

SYNOPSIS

       int __break_lease(struct inode * inode, unsigned int mode, unsigned int type);

ARGUMENTS

       inode
	   the inode of the file to return

       mode

DESCRIPTION

       break_lease (inlined for speed) has checked there already is at least some kind of lock (maybe a lease) on this file. Leases are broken on

NAME

       dhclient.leases - DHCP client lease database

DESCRIPTION

       The  Internet  Software Consortium DHCP client keeps a persistent database of leases that it has acquired that are still valid.	 The data-
       base is a free-form ASCII file containing one valid declaration per lease.   If more than one declaration appears for a	given  lease,  the
       last one in the file is used.   The file is written as a log, so this is not an unusual occurrance.

       The format of the lease declarations is described in dhclient.conf(5).

FILES

       /var/lib/dhcp/dhclient.leases
