This is a note to let you know that I've just added the patch titled scsi: qla2xxx: Send Notify ACK after N2N PLOGI to the 5.4-stable tree which can be found at: http://www.kernel.org/git/?p=linux/kernel/git/stable/stable-queue.git;a=summary The filename of the patch is: scsi-qla2xxx-send-notify-ack-after-n2n-plogi.patch and it can be found in the queue-5.4 subdirectory. If you, or anyone else, feels it should not be added to the stable tree, please let <stable@xxxxxxxxxxxxxxx> know about it. commit 32df77c20e5476f54eb2d699df3e4ca75e6fd697 Author: Roman Bolshakov <r.bolshakov@xxxxxxxxx> Date: Mon Nov 25 19:56:59 2019 +0300 scsi: qla2xxx: Send Notify ACK after N2N PLOGI [ Upstream commit 5e6b01d84b9d20bcd77fc7c4733a2a4149bf220a ] qlt_handle_login schedules session for deletion even if a login is in progress. That causes login bouncing, i.e. a few logins are made before it settles down. Complete the first login by sending Notify Acknowledge IOCB via qlt_plogi_ack_unref if the session is pending login completion.
