From b5bf6d681fce69cd1a57bfc0f1bdbbb348035117 Mon Sep 17 00:00:00 2001 From: Justin Tee Date: Mon, 15 Sep 2025 11:08:02 -0700 Subject: [PATCH] scsi: lpfc: Decrement ndlp kref after FDISC retries exhausted The kref for Fabric_DID ndlps is not decremented after repeated FDISC failures and exhausting maximum allowed retries. This can leave the ndlp lingering unnecessarily. Add a test and set bit operation for the NLP_DROPPED flag. If not previously set, then a kref is decremented. The ndlp is freed when the remaining reference for the completing ELS is put. Signed-off-by: Justin Tee Message-ID: <20250915180811.137530-6-justintee8345@gmail.com> Signed-off-by: Martin K.
