This fixes a bug where the iscsi class/driver did not do a put_device
when a sess/conn device was found. This also simplifies the interface
by not having to pass in some arguments that were duplicated and did
not need to be exported.Reported-by: Zhao Hongjiang

These enums have been separate since the dawn of SAS, mainly because the
latter is a procotol only enum and the former includes additional state
for libsas. The dichotomy causes endless confusion about which one you
should use where and leads to pointless warnings like this:drivers/scsi/mvsas/mv_sas.c: In function 'mvs_update_phyinfo':
drivers/scsi/mvsas/mv_sas.c:1162:34: warning: comparison between 'enum sas_device_type' and 'enum sas_dev_type' [-Wenum-compare]Fix by eliminating one of them. The one kept is effectively the sas.h
one, but call it sas_device_type and make sure the enums are all
properly namespaced with the SAS_ prefix.Signed-off-by: James Bottomley

scsi_send_eh_cmnd() is calling queuecommand() directly, so
it needs to check the return value here.
The only valid return codes for queuecommand() are 'busy'
states, so we need to wait for a bit to allow the LLDD
to recover.Based on an earlier patch from Wen Xiong.

Commit 8a965b3baa89 ("mm, slab_common: Fix bootstrap creation of kmalloc
caches") introduced a regression that caused us to crash early during
boot. The commit was introducing ordering of slab creation, making sure
two odd-sized slabs were created after specific powers of two sizes.But, if any of the power of two slabs were created earlier during boot,
slabs at index 1 or 2 might not get created at all. This patch makes
sure none of the slabs get skipped.Tony Lindgren bisected this down to the offending commit, which really
helped because bisect kept bringing me to almost but not quite this one.Signed-off-by: Chris Mason

After build_free_nids() searches free nid candidates from nat pages and
current journal blocks, it checks all the candidates if they are allocated
so that the nat cache has its nid with an allocated block address.In this procedure, previously we used
list_for_each_entry_safe(fnid, next_fnid, &nm_i->free_nid_list, list).
But, this is not covered by free_nid_list_lock, resulting in null pointer bug.This patch moves this checking routine inside add_free_nid() in order not to use
the spin_lock.Signed-off-by: Jaegeuk Kim

This patch does two cleanups:
1. remove unused variable "fcnt" in build_free_nids().

Directly drop the free_nid cache when nm_i->fcnt > 2 * MAX_FREE_NIDS
Since there is NOT nmi->free_nid_list_lock spinlock protection between
a sequential calling of alloc_nid() and alloc_nid_failed(), some other
threads may already add new free_nid to the free_nid_list during this
period.We need to make sure nmi->fcnt is never > 2 * MAX_FREE_NIDS.

When unable to roll forward the journal, we shouldn't bail out and

The bitops prototype use an 'int' as the bit index type but the asm

ESR.WnR bit is always set on data cache maintenance faults even though
the page is not required to have write permission. If a translation
fault (page not yet mapped) happens for read-only user address range,
Linux incorrectly assumes a permission fault. This patch adds the check
of the ESR.CM bit during the page fault handling to ignore the 'write'
flag.Signed-off-by: Catalin Marinas

Commit 90556ca1 ("arm64: vexpress: Add dts files for the ARMv8 RTSM
models") added foundation-v8.dts, but erroneously set
/cpus/#address-cells = while providing two cells in each cpus/cpu@N
node's reg property.As of commit ea393a2e ("arm64: smp: honour #address-size when parsing
CPU reg property") we read in as many address cells as specified rather
than always reading two. This means that for foundation-v8.dts, we only
read the first reg cell (zero) for each cpu node, and receive a lot of
warnings at boot of the form "/cpus/cpu@1: duplicate cpu reg properties
in the DT".This patch corrects foundation-v8.dts to have the correct value for
/cpus/#address-cells.Signed-off-by: Mark Rutland
