__break_lease - revoke all outstanding leases on file
int __break_lease(struct inode * inode, unsigned int mode, unsigned int type);
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 a call to open or truncate. This function can sleep unless you specified O_NONBLOCK to your open.
