f7521fbcab ("Fix RCU handling of scsi_device.vpd_pg8[03]"): drivers/scsi/scsi.c:477 suspicious rcu_dereference_check() usage!
by kernel test robot
Greetings,
0day kernel testing robot got the below dmesg and the first bad commit is
https://github.com/0day-ci/linux/commits/Bart-Van-Assche/SCSI-patches-for...
commit f7521fbcab6449577424a753782c32ba7dffaf59
Author: Bart Van Assche <bart.vanassche(a)wdc.com>
AuthorDate: Wed Aug 23 14:39:57 2017 -0700
Commit: 0day robot <fengguang.wu(a)intel.com>
CommitDate: Fri Aug 25 09:40:43 2017 +0800
Fix RCU handling of scsi_device.vpd_pg8[03]
Only annotate pointers that are shared across threads with __rcu.
Use rcu_dereference() when dereferencing an RCU pointer. Protect
also the RCU pointer dereferences when freeing RCU pointers. This
patch suppresses about twenty sparse complaints about the vpd_pg8[03]
pointers.
Fixes: commit 09e2b0b14690 ("scsi: rescan VPD attributes")

a25339d553 ("x86/idt: Hide set_intr_gate()"): WARNING: CPU: 0 PID: 0 at arch/x86/kernel/idt.c:355 update_intr_gate
by kernel test robot
Greetings,
0day kernel testing robot got the below dmesg and the first bad commit is
https://git.kernel.org/pub/scm/linux/kernel/git/tip/tip.git WIP.x86/apic
commit a25339d55320c73fd253fbf188c27abd4550d13a
Author: Thomas Gleixner <tglx(a)linutronix.de>
AuthorDate: Thu Aug 24 16:38:36 2017 +0200

CommitDate: Fri Aug 25 12:27:50 2017 +0200
x86/idt: Hide set_intr_gate()
set_intr_gate() is an internal function of the IDT code. The only user left
is the KVM code which replaces the pagefault handler eventually.
Provide an explicit update_intr_gate() function and make set_intr_gate()
static. While at it replace the magic number 14 in the KVM code with the
proper trap define.

drm: Clean up connectors by unreferencing them
Only static connectors should be left at this point, and we should be
able to clean them out by simply dropping that last reference still
around from drm_connector_init.
If that leaves anything behind then we have a driver bug.
Doing the final cleanup this way also allows us to use
drm_connector_iter, removing the very last place where we walk
connector_list explicitly in drm core&helpers.

writeback: introduce super_operations->write_metadata
Now that we have metadata counters in the VM, we need to provide a way to kick
writeback on dirty metadata. Introduce super_operations->write_metadata. This
allows file systems to deal with writing back any dirty metadata we need based
on the writeback needs of the system. Since there is no inode to key off of we
need a list in the bdi for dirty super blocks to be added. From there we can
find any dirty sb's on the bdi we are currently doing writeback on and call into
their ->write_metadata callback.
