In the Linux kernel, the following vulnerability has been resolved:
scsi: lpfc: Fix hard lockup when reading the rx_monitor from debugfs
During I/O and simultaneous cat of /sys/kernel/debug/lpfc/fnX/rx_monitor, a
hard lockup similar to the call trace below may occur.
The spin_lock_bh in lpfc_rx_monitor_report is not protecting from timer
interrupts as expected, so change the strength of the spin lock to _irq.
