Re: [PATCH 4/5] gfs2: stop giving out non-cluster-coherent leases

This is the return code that setlease() currently returns when the lease 
can not be obtained. Although ENOTSUPP would be more accurately describing 
the error it will be a new return code from setlease() that is currently 
not expected by callers to setlease(), but either return code should work.
