From 411c9699dfe346fe7e70734c34291ea83d9b70b5 Mon Sep 17 00:00:00 2001 From: "John L. Hammond" Date: Mon, 20 Jun 2016 16:55:25 -0400 Subject: [PATCH] staging/lustre/llite: correct request handling after ll_lookup_it() In the FIFO cases of ll_atomic_open() and ll_lookup_nd() remove spurious calls to ptlrpc_req_finished(). Explain that these cases are unreachable in practice anyway. Signed-off-by: John L.
