From f4b830c61b5b54c278e17eb19c696db0d6e68373 Mon Sep 17 00:00:00 2001 From: Christophe JAILLET Date: Fri, 21 Aug 2020 09:58:19 +0200 Subject: [PATCH] nvmet-fc: Fix a missed _irqsave version of spin_lock in 'nvmet_fc_fod_op_done()' [ Upstream commit 70e37988db94aba607d5491a94f80ba08e399b6b ] The way 'spin_lock()' and 'spin_lock_irqsave()' are used is not consistent in this function. Use 'spin_lock_irqsave()' also here, as there is no guarantee that interruptions are disabled at that point, according to surrounding code.
