From 35a61606a61249fb59cbf566f869c026f5fafec4 Mon Sep 17 00:00:00 2001 From: Anna Schumaker Date: Tue, 11 Sep 2018 16:23:47 -0400 Subject: [PATCH] NFS: Reduce indentation of the switch statement in nfs4_reclaim_open_state() Most places in the kernel tend to line up cases with the switch to reduce indentation, so move this over to match that style. Additionally, I handle the (status >= 0) case in the switch so that we only "goto restart" from a single place after error handling.
