In the Linux kernel, the following vulnerability has been resolved:
scsi: bnx2fc: Remove spin_lock_bh while releasing resources after upload
The session resources are used by FW and driver when session is offloaded, once session is uploaded these resources are not used. The lock is not required as these fields won't be used any longer. The offload and upload calls are sequential, hence lock is not required.
This will suppress following BUG_ON():
