Subject: pnfs: Increase the refcount when LAYOUTGET fails the first time
From: Yanchuan Nian <[email protected]>
commit 39e88fcfb1d5c6c4b1ff76ca2ab76cf449b850e8 upstream.
The layout will be set unusable if LAYOUTGET fails. Is it reasonable to
increase the refcount iff LAYOUTGET fails the first time?
