From: Madhuparna Bhowmik <madhuparnabhowmik04@xxxxxxxxx> This patch fixes the following errors: fs/nfs/dir.c:2353:14: error: incompatible types in comparison expression (different address spaces): fs/nfs/dir.c:2353:14: struct list_head [noderef] <asn:4> * fs/nfs/dir.c:2353:14: struct list_head * caused due to directly accessing the prev pointer of a RCU protected list. Accessing the pointer using the macro list_prev_rcu() fixes this error.
