refcount_t type and corresponding API should be
used instead of atomic_t when the variable is used as
a reference counter. This allows to avoid accidental
refcounter overflows that might lead to use-after-free
situations.

The subject is wrong, should be something like "scsi: libfc convert
fc_fcp_pkt.ref_cnt from atomic_t to refcount_t" but not s390.

Other than that
