From 0948a9c5386095baae4012190a6b65aba684a907 Mon Sep 17 00:00:00 2001 From: James Smart jsmart2021@gmail.com Date: Fri, 1 Jul 2022 14:14:17 -0700 Subject: [PATCH] scsi: lpfc: Remove extra atomic_inc on cmd_pending in queuecommand after VMID

VMID introduced an extra increment of cmd_pending, causing double-counting of the I/O. The normal increment ios performed in lpfc_get_scsi_buf.
