Hi all,

After merging the scsi-mkp tree, today's linux-next build (arm64
defconfig) produced this warning:

That commit is now in Linus' tree.

BTW, James, I tried to use your HansenPartnership.com email address, but
the DNS is giving SERVER FAIL errors for it ...

Should be fixed now.  An update in debian testing changed the way
dnssec works with bind9 and effectively caused a roll of my zone
signing key (or more accurately moved me from a separated ZSK KSK pair
to a combined key).  Anyway, since there was no DS record for the new
key the whole domain broke.  I've now fixed the delegation and it's
working again.

I am still getting this warning, but it is now after the merge of the

linux-next: build warning after merge of the scsi-mkp tree

[Stephen Rothwell]

[-- Attachment #1: Type: text/plain, Size: 1096 bytes --]

Hi all,

After merging the scsi-mkp tree, today's linux-next build (x86_64
allmodconfig) produced this warning:

drivers/scsi/smartpqi/smartpqi_init.c: In function 'pqi_build_raid_path_request':

Introduced by commit

  171c28653a2d ("scsi: smartpqi: turn off lun data caching for ptraid")

This due to my use of -Wimplicit-fallthrough for Kees Cook.  This is
new code.  The warning can be suppressed by adding a comment like

  /* fall through */

just above the following "case" or "default" to indicate that the
fallthrough is intended.

It is actually complaining about function fc_rport_recv_plogi_req()

linux-next: build warning after merge of the scsi-mkp tree

[Stephen Rothwell]

Hi Martin,

After merging the scsi-mkp tree, today's linux-next build (x86_64
allmodconfig) produced this warning:

drivers/scsi/hisi_sas/hisi_sas_main.c: In function 'hisi_sas_controller_reset':
drivers/scsi/hisi_sas/hisi_sas_main.c:1049:24: warning: unused variable 'sas_ha' [-Wunused-variable]
  struct sas_ha_struct *sas_ha = &hisi_hba->sha;
                        ^

Introduced by commit

  042ebd293b86 ("scsi: libsas: kill useless ha_event and do some cleanup")
