2018-12-18scsi: flip the default on use_clusteringChristoph Hellwig
Most SCSI drivers want to enable "clustering", that is merging of segments so that they might span more than a single page. Remove the ENABLE_CLUSTERING define, and require drivers to explicitly set DISABLE_CLUSTERING to disable this feature. Signed-off-by: Christoph Hellwig <hch@lst.de> Signed-off-by: Martin K.

2018-06-12treewide: kzalloc() -> kcalloc()Kees Cook
The kzalloc() function has a 2-factor argument form, kcalloc(). This patch replaces cases of: kzalloc(a * b, gfp) with: kcalloc(a * b, gfp) as well as handling cases of: kzalloc(a * b * c, gfp) with: kzalloc(array3_size(a, b, c), gfp) as it's slightly less ugly than: kzalloc_array(array_size(a, b), c, gfp) This does, however, attempt to ignore constant size factors like: kzalloc(4 * 1024, gfp) though any constants defined via macros get caught up in the conversion.

git://git.kernel.org/pub/scm/linux/kernel/git/nvdimm/nvdimm Pull libnvdimm updates from Dan Williams: "This update has successfully completed a 0day-kbuild run and has appeared in a linux-next release. The changes outside of the typical drivers/nvdimm/ and drivers/acpi/nfit.[ch] paths are related to the removal of IORESOURCE_CACHEABLE, the introduction of memremap(), and the introduction of ZONE_DEVICE + devm_memremap_pages(). Summary: - Introduce ZONE_DEVICE and devm_memremap_pages() as a generic mechanism for adding device-driver-discovered memory regions to the kernel's direct map. This facility is used by the pmem driver to enable pfn_to_page() operations on the page frames returned by DAX ('direct_access' in 'struct block_device_operations'). For now, the 'memmap' allocation for these "device" pages comes from "System RAM". Support for allocating the memmap from device memory will arrive in a later kernel. - Introduce memremap() to replace usages of ioremap_cache() and ioremap_wt(). memremap() drops the __iomem annotation for these mappings to memory that do not have i/o side effects. The replacement of ioremap_cache() with memremap() is limited to the pmem driver to ease merging the api change in v4.3. Completion of the conversion is targeted for v4.4. - Similar to the usage of memcpy_to_pmem() + wmb_pmem() in the pmem driver, update the VFS DAX implementation and PMEM api to provide persistence guarantees for kernel operations on a DAX mapping. - Convert the ACPI NFIT 'BLK' driver to map the block apertures as cacheable to improve performance. - Miscellaneous updates and fixes to libnvdimm including support for issuing "address range scrub" commands, clarifying the optimal 'sector size' of pmem devices, a clarification of the usage of the ACPI '_STA' (status) property for DIMM devices, and other minor fixes" * tag 'libnvdimm-for-4.3' of git://git.kernel.org/pub/scm/linux/kernel/git/nvdimm/nvdimm: (34 commits) libnvdimm, pmem: direct map legacy pmem by default libnvdimm, pmem: 'struct page' for pmem libnvdimm, pfn: 'struct page' provider infrastructure x86, pmem: clarify that ARCH_HAS_PMEM_API implies PMEM mapped WB add devm_memremap_pages mm: ZONE_DEVICE for "device memory" mm: move __phys_to_pfn and __pfn_to_phys to asm/generic/memory_model.h dax: drop size parameter to ->direct_access() nd_blk: change aperture mapping from WC to WB nvdimm: change to use generic kvfree() pmem, dax: have direct_access use __pmem annotation dax: update I/O path to do proper PMEM flushing pmem: add copy_from_iter_pmem() and clear_pmem() pmem, x86: clean up conditional pmem includes pmem: remove layer when calling arch_has_wmb_pmem() pmem, x86: move x86 PMEM API to new pmem.h header libnvdimm, e820: make CONFIG_X86_PMEM_LEGACY a tristate option pmem: switch to devm_ allocations devres: add devm_memremap libnvdimm, btt: write and validate parent_uuid ...

2015-08-10cleanup IORESOURCE_CACHEABLE vs ioremap()Dan Williams
Quoting Arnd: I was thinking the opposite approach and basically removing all uses of IORESOURCE_CACHEABLE from the kernel. There are only a handful of them.and we can probably replace them all with hardcoded ioremap_cached() calls in the cases they are actually useful. All existing usages of IORESOURCE_CACHEABLE call ioremap() instead of ioremap_nocache() if the resource is cacheable, however ioremap() is uncached by default. Clearly none of the existing usages care about the cacheability. Particularly devm_ioremap_resource() never worked as advertised since it always fell back to plain ioremap(). Clean this up as the new direction we want is to convert ioremap_<type>() usages to memremap(..., flags).

fill_result_tf() grabs the taskfile flags from the originating qc which sas_ata_qc_fill_rtf() promptly overwrites. The presence of an ata_taskfile in the sata_device makes it tempting to just copy the full contents in sas_ata_qc_fill_rtf(). However, libata really only wants the fis contents and expects the other portions of the taskfile to not be touched by ->qc_fill_rtf. To that end store a fis buffer in the sata_device and use ata_tf_from_fis() like every other ->qc_fill_rtf() implementation.

2012-02-29[SCSI] libsas: don't recover end devices attached to disabled physDan Williams
If userspace has decided to disable a phy the kernel should honor that and not inadvertantly re-enable the phy via error recovery. This is more straightforward in the sata case where link recovery (via libata-eh) is separate from sas_task cancelling in libsas-eh. Teach libsas to accept -ENODEV as a successful response from I_T_nexus_reset ('successful' in terms of not escalating further). This is a more comprehensive fix then "libsas: don't recover 'gone' devices in sas_ata_hard_reset()", as it is no longer sata-specific. aic94xx does check the return value from sas_phy_reset() so if the phy is disabled we proceed with clearing the I_T_nexus.

2012-02-29[SCSI] libsas: async ata scanningDan Williams
libsas ata error handling is already async but this does not help the scan case. Move initial link recovery out from under host->scan_mutex, and delay synchronization with eh until after all port probe/recovery work has been queued. Device ordering is maintained with scan order by still calling sas_rphy_add() in order of domain discovery. Since we now scan the domain list when invoking libata-eh we need to be careful to check for fully initialized ata ports.

2012-02-29[SCSI] libsas: fix sas_find_local_phy(), take phy referencesDan Williams
In the direct-attached case this routine returns the phy on which this device was first discovered. Which is broken if we want to support wide-targets, as this phy reference can become stale even though the port is still active. In the expander-attached case this routine tries to lookup the phy by scanning the attached sas addresses of the parent expander, and BUG_ONs if it can't find it. However since eh and the libsas workqueue run independently we can still be attempting device recovery via eh after libsas has recorded the device as detached. This is even easier to hit now that eh is blocked while device domain rediscovery takes place, and that libata is fed more timed out commands increasing the chances that it will try to recover the ata device. Arrange for dev->phy to always point to a last known good phy, it may be stale after the port is torn down, but it will catch up for wide port reconfigurations, and never be NULL.

2012-02-19[SCSI] libsas: use ->set_dmamode to notify lldds of NCQ parametersDan Williams
sas_discover_sata() notifies lldds of sata devices twice. Once to allow the 'identify' to be sent, and a second time to allow aic94xx (the only libsas driver that cares about sata_dev.identify) to setup NCQ parameters before the device becomes known to the midlayer. Replace this double notification and intervening 'identify' with an explicit ->lldd_ata_set_dmamode notification. With this change all ata internal commands are issued by libata, so we no longer need sas_issue_ata_cmd(). The data from the identify command only needs to be cached in one location so ata_device.id replaces domain_device.sata_dev.identify.

2012-02-19[SCSI] libsas: introduce sas_drain_work()Dan Williams
When an lldd invokes ->notify_port_event() it can trigger a chain of libsas events to: 1/ form the port and find the direct attached device 2/ if the attached device is an expander perform domain discovery A call to flush_workqueue() will only flush the initial port formation work. Currently libsas users need to call scsi_flush_work() up to the max depth of chain (which will grow from 2 to 3 when ata discovery is moved to its own discovery event). Instead of open coding multiple calls switch to use drain_workqueue() to flush sas work. drain_workqueue() does not handle new work submitted during the drain so libsas needs a bit of infrastructure to hold off unchained work submissions while a drain is in flight. A lldd ->notify() event is considered 'unchained' while a sas_discover_event() is 'chained'. As Tejun notes: "For now, I think it would be best to add private wrapper in libsas to support deferring unchained work items while draining."
