Subject: [PATCH 4/9] lpfc: Eliminate unnecessary relocking in lpfc_check_nlp_post_devloss
Date: Tue, 31 Oct 2023 12:12:19 -0700 [thread overview]
Message-ID: <20231031191224.150862-5-justintee8345@gmail.com> (raw)
In-Reply-To: <20231031191224.150862-1-justintee8345@gmail.com>
In lpfc_check_nlp_post_devloss, retaking of the ndlp lock in the if
statement is useless because the very next line unlocks. Simply, return
to avoid relocking.
