From fd57a687d44118c0a3859f61a110f6e12804dd16 Mon Sep 17 00:00:00 2001 From: Justin Tee Date: Tue, 23 May 2023 11:31:59 -0700 Subject: [PATCH] scsi: lpfc: Clear NLP_IN_DEV_LOSS flag if already in rediscovery In dev_loss_tmo callback routine, we early return if the ndlp is in a state of rediscovery. This occurs when a target proactively PLOGIs or PRLIs after an RSCN before the dev_loss_tmo callback routine is scheduled to run. Move clear of the NLP_IN_DEV_LOSS flag before the ndlp state check in such cases.
