Hi all, After merging the scsi-mkp tree, today's linux-next build (x86_64 allmodconfig) produced this warning:
In file included from include/linux/spinlock_types.h:18:0,
from include/linux/spinlock.h:82,
from drivers/scsi/libfc/fc_rport.c:61:
drivers/scsi/libfc/fc_rport.c: In function 'fc_rport_recv_req':
include/linux/lockdep.h:347:45: warning: 'rdata' may be used uninitialized in
this function [-Wmaybe-uninitialized]
#define lockdep_is_held(lock) lock_is_held(&(lock)->dep_map)
^
drivers/scsi/libfc/fc_rport.c:1832:24: note: 'rdata' was declared here
struct fc_rport_priv *rdata;
^~~~~
Introduced by commit
ee35624e1e4e ("scsi: libfc: Add lockdep annotations")
It is actually complaining about function fc_rport_recv_plogi_req()
(presumably it is being inlined) and this looks like an actual bug :-(
