scsi: libfc: pass an error pointer to fc_disc_error()

2017-07-12T21:25:12Z

This patch is basically to silence a static checker warning. drivers/scsi/libfc/fc_disc.c:326 fc_disc_error() warn: passing a valid pointer to 'PTR_ERR' It doesn't affect runtime because it treats -ENOMEM and a valid pointer the same. But the documentation says we should be passing an error pointer. Signed-off-by: Dan Carpenter Acked-by: Johannes Thumshirn Signed-off-by: Martin K. Petersen

sched/headers: Prepare to use instead of in

2017-03-02T07:42:38Z

We don't actually need the full rculist.h header in sched.h anymore, we will be able to include the smaller rcupdate.h header instead. But first update code that relied on the implicit header inclusion.

scsi: libfc: Replace ->rport_flush_queue callback with function call

2016-11-08T22:29:55Z

The ->rport_flush_queue callback only ever had a single implementation, so we can as well call it directly and drop the callback. Signed-off-by: Hannes Reinecke Acked-by: Johannes Thumshirn Signed-off-by: Martin K. Petersen

scsi: libfc: Fixup disc_mutex handling

2016-11-08T22:29:46Z

The list of attached 'rdata' remote port structures is RCU protected, so there is no need to take the 'disc_mutex' when traversing it. Rather we should be using rcu_read_lock() and kref_get_unless_zero() to validate the entries. We need, however, take the disc_mutex when deleting an entry; otherwise we risk clashes with list_add.
