Subject[PATCH AUTOSEL 4.18 063/131] nfs: Referrals not inheriting proto setting from parent
Date
From: Calum Mackay <calum.mackay@oracle.com>

[ Upstream commit 23a88ade7131aa259c532ab17685c76de562242b ]

Commit 530ea4219231 ("nfs: Referrals should use the same proto setting
as their parent") encloses the fix with #ifdef CONFIG_SUNRPC_XPRT_RDMA.

CONFIG_SUNRPC_XPRT_RDMA is a tristate option, so it should be tested
with #if IS_ENABLED().
