From 6e47666ef93dc9c4011407df8d2de1dd1ed39f25 Mon Sep 17 00:00:00 2001 From: Xiyu Yang <xiyuyang19@fudan.edu.cn> Date: Sat, 25 Apr 2020 21:04:40 +0800 Subject: NFSv4: Remove unreachable error condition due to rpc_run_task() nfs4_proc_layoutget() invokes rpc_run_task(), which return the value to "task". Since rpc_run_task() is impossible to return an ERR pointer, there is no need to add the IS_ERR() condition on "task" here. So we need to remove it.
