scsi: libfc: free response frame from GPN_ID

2020-02-21T22:56:32Z

fc_disc_gpn_id_resp() should be the last function using it so free it here to avoid memory leak. Link: https://lore.kernel.org/r/1579013000-14570-2-git-send-email-igor.druzhinin@citrix.com Reviewed-by: Hannes Reinecke Signed-off-by: Igor Druzhinin Signed-off-by: Martin K. Petersen

scsi: libfc: hold disc_mutex in fc_disc_stop_rports()

2018-07-13T03:01:16Z

fc_disc_stop_rports() is calling fc_rport_logoff(), which in turn is acquiring the rport mutex. So we cannot use RCU list traversal here, but rather need to hold the disc mutex to avoid list corruption while traversing.

scsi: libfc: fixup 'sleeping function called from invalid context'

2018-07-11T02:42:47Z

fc_rport_login() will be calling mutex_lock() while running inside an RCU-protected section, triggering the warning 'sleeping function called from invalid context'. To fix this we can drop the rcu functions here altogether as the disc mutex protecting the list itself is already held, preventing any list manipulation.

scsi: libfc: remove redundant initialization of 'disc'

2018-02-14T02:37:01Z

Pointer disc is being intializated a value that is never read and then re-assigned the same value later on, hence the initialization is redundant and can be removed.

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.
