[PATCH v2] SUNRPC: Remove unreachable error condition

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



rpc_clnt_test_and_add_xprt() invokes rpc_call_null_helper(), which
return the value of rpc_run_task() 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.

Fixes: 7f554890587c ("SUNRPC: Allow addition of new transports to a
struct rpc_clnt")

Changes in v2:
- Remove useless IS_ERR check instead of fixing a refcnt leak in this
error path
