From 37c893e36b1b538aea15bcef6330e1d4a7b77583 Mon Sep 17 00:00:00 2001 From: Justin Tee Date: Wed, 18 Jun 2025 12:21:29 -0700 Subject: [PATCH] scsi: lpfc: Skip RSCN processing when FC_UNLOADING flag is set During rmmod, all ndlp objects are cleaned up and marked with the NLP_DROPPED flag indicating that an ndlp object is currently being released. Thus, if an RSCN is received during driver unload, then walking the fc_nodes list to process the RSCN is unnecessary because the ndlp objects are very shortly going to be released. In the lpfc_rscn_recovery_check routine, early return if the driver is in the middle of unloading by checking for the FC_UNLOADING flag.
