Subject: [PATCH 5.12 30/48] scsi: target: core: Fix warning on realtime kernels
From: Maurizio Lombardi <mlombard@...hat.com>
[ Upstream commit 515da6f4295c2c42b8c54572cce3d2dd1167c41e ]
On realtime kernels, spin_lock_irq*(spinlock_t) do not disable the
interrupts, a call to irqs_disabled() will return false thus firing a
warning in __transport_wait_for_tasks().
Remove the warning and also replace assert_spin_locked() with
lockdep_assert_held()
