From 8ef659f1a840c953a59442ff1400ec73baf3b601 Mon Sep 17 00:00:00 2001 From: Karsten Graul Date: Thu, 11 Apr 2019 11:17:33 +0200 Subject: [PATCH] net/smc: fix return code from FLUSH command The FLUSH command is used to empty the pnet table. No return code is expected from the command. Commit a9d8b0b1e3d6 added namespace support for the pnet table and changed the FLUSH command processing to call smc_pnet_remove_by_pnetid() to remove the pnet entries. This function returns -ENOENT when no entry was deleted, which is now the return code of the FLUSH command. As a result the FLUSH command will return an error when the pnet table is already empty. Restore the expected behavior and let FLUSH always return 0.
