| 2017-11-15 | mm: remove __GFP_COLD | Mel Gorman | |
| As the page free path makes no distinction between cache hot and cold pages, there is no real useful ordering of pages in the free list that allocation requests can take advantage of. Juding from the users of __GFP_COLD, it is likely that a number of them are the result of copying other sites instead of actually measuring the impact. Remove the __GFP_COLD parameter which simplifies a number of paths in the page allocator. This is potentially controversial but bear in mind that the size of the per-cpu pagelists versus modern cache sizes means that the whole per-cpu list can often fit in the L3 cache. Hence, there is only a potential benefit for microbenchmarks that alloc/free pages in a tight loop. It's even worse when THP is taken into account which has little or no chance of getting a cache-hot page as the per-cpu list is bypassed and the zeroing of multiple pages will thrash the cache anyway. The truncate microbenchmarks are not shown as this patch affects the allocation path and not the free path. A page fault microbenchmark was tested but it showed no sigificant difference which is not surprising given that the __GFP_COLD branches are a miniscule percentage of the fault path.

| 2017-11-15 | mm: remove cold parameter for release_pages | Mel Gorman | |
| All callers of release_pages claim the pages being released are cache hot. As no one cares about the hotness of pages being released to the allocator, just ditch the parameter. No performance impact is expected as the overhead is marginal. The parameter is removed simply because it is a bit stupid to have a useless parameter copied everywhere.

| 2017-11-15 | kmemcheck: remove annotations | Levin, Alexander (Sasha Levin) | |
| Patch series "kmemcheck: kill kmemcheck", v2. As discussed at LSF/MM, kill kmemcheck. KASan is a replacement that is able to work without the limitation of kmemcheck (single CPU, slow). KASan is already upstream. We are also not aware of any users of kmemcheck (or users who don't consider KASan as a suitable replacement). The only objection was that since KASAN wasn't supported by all GCC versions provided by distros at that time we should hold off for 2 years, and try again. Now that 2 years have passed, and all distros provide gcc that supports KASAN, kill kmemcheck again for the very same reasons. This patch (of 4): Remove kmemcheck annotations, and calls to kmemcheck from the kernel. [alexander.levin@verizon.com: correctly remove kmemcheck call from dma_map_sg_attrs] Link: http://lkml.kernel.org/r/20171012192151.26531-1-alexander.levin@verizon.com Link: http://lkml.kernel.org/r/20171007030159.22241-2-alexander.levin@verizon.com Signed-off-by: Sasha Levin <alexander.levin@verizon.com> Cc: Alexander Potapenko <glider@google.com> Cc: Eric W.

| 2017-11-15 | bdi: introduce BDI_CAP_SYNCHRONOUS_IO | Minchan Kim | |
| As discussed at https://lkml.kernel.org/r/<20170728165604.10455-1-ross.zwisler@linux.intel.com> someday we will remove rw_page(). If so, we need something to detect such super-fast storage on which synchronous IO operations like the current rw_page are always a win. Introduces BDI_CAP_SYNCHRONOUS_IO to indicate such devices. With it, we could use various optimization techniques.

| 2017-11-15 | zram: set BDI_CAP_STABLE_WRITES once | Minchan Kim | |
| With fast swap storage, the platform wants to use swap more aggressively and swap-in is crucial to application latency. The rw_page() based synchronous devices like zram, pmem and btt are such fast storage. When I profile swapin performance with zram lz4 decompress test, S/W overhead is more than 70%. Maybe, it would be bigger in nvdimm. This patchset reduces swap-in latency by skipping swapcache if the swap device is a synchronous device like a rw_page() based device. It enhances by 45% my swapin test (5G sequential swapin, no readahead) from 2.41sec to 1.64sec. This patch (of 4): Commit 19b7ccf8651d ("block: get rid of blk_integrity_revalidate()") fixed a weird thing (i.e., reset BDI_CAP_STABLE_WRITES flag unconditionally whenever revalidat_disk is called) so zram doesn't need to reset the flag any more when revalidating the bdev. Instead, set the flag just once when the zram device is created. It shouldn't change any behavior.

| Pull IPMI updates from Corey Minyard: "This is a fairly large rework of the IPMI code, along with a bunch of smaller fixes. The major changes have been in the next tree for a couple of months, so they should be good to do in. - Some users had IPMI systems where the GUID of the IPMI controller could change. So rescanning of the GUID was added. The naming of some sysfs things was dependent on the GUID, however, so this resulted in the sysfs interface code in IPMI changing to remove that dependency and name the IPMI BMCs like other sysfs devices. - The ipmi_si_intf.c code was fairly bloated with all the different discovery methods (PCI, ACPI, SMBIOS, OF, platform, module parameters, hot add). The structure of how the interfaces were added was redone to make them more modular, then the individual methods were pulled out into their own files" * tag 'ipmi-for-4.15' of git://github.com/cminyard/linux-ipmi: (48 commits) ipmi_si: Delete an error message for a failed memory allocation in try_smi_init() ipmi_si: fix memory leak on new_smi ipmi: remove redundant initialization of bmc ipmi: pr_err() strings should end with newlines ipmi: Clean up some print operations ipmi: Make the DMI probe into a generic platform probe ipmi: Make the IPMI proc interface configurable ipmi_ssif: Add device attrs for the things in proc ipmi_si: Add device attrs for the things in proc ipmi_si: remove ipmi_smi_alloc() function ipmi_si: Move port and mem I/O handling to their own files ipmi_si: Get rid of unused spacing and port fields ipmi_si: Move PARISC handling to another file ipmi_si: Move PCI setup to another file ipmi_si: Move platform device handling to another file ipmi_si: Move hardcode handling to a separate file. ipmi_si: Move the hotmod handling to another file. ipmi_si: Change ipmi_si_add_smi() to take just I/O info ipmi_si: Move io setup into io structure ipmi_si: Move irq setup handling into the io struct ... | |||

Everything in this pull request has been through 0day and at least two days of linux-next (since Stephen doesn't necessarily flag new errors/warnings until day2). A few more items (about 30 patches) from Intel and Mellanox showed up on the list on Tuesday. I've excluded those from this pull request, and I'm sure some of them qualify as fixes suitable to send any time, but I still have to review them fully. If they contain mostly fixes and little or no new development, then I will probably send them through by the end of the week just to get them out of the way. There was a break in my acceptance of patches which coincides with the computer problems I had, and then when I got things mostly back under control I had a backlog of patches to process, which I did mostly last Friday and Monday. So there is a larger number of patches processed in that timeframe than I was striving for. Summary: - Add iWARP support to qedr driver - Lots of misc fixes across subsystem - Multiple update series to hns roce driver - Multiple update series to hfi1 driver - Updates to vnic driver - Add kref to wait struct in cxgb4 driver - Updates to i40iw driver - Mellanox shared pull request - timer_setup changes - massive cleanup series from Bart Van Assche - Two series of SRP/SRPT changes from Bart Van Assche - Core updates from Mellanox - i40iw updates - IPoIB updates - mlx5 updates - mlx4 updates - hns updates - bnxt_re fixes - PCI write padding support - Sparse/Smatch/warning cleanups/fixes - CQ moderation support - SRQ support in vmw_pvrdma" * tag 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/dledford/rdma: (296 commits) RDMA/core: Rename kernel modify_cq to better describe its usage IB/mlx5: Add CQ moderation capability to query_device IB/mlx4: Add CQ moderation capability to query_device IB/uverbs: Add CQ moderation capability to query_device IB/mlx5: Exposing modify CQ callback to uverbs layer IB/mlx4: Exposing modify CQ callback to uverbs layer IB/uverbs: Allow CQ moderation with modify CQ iw_cxgb4: atomically flush the qp iw_cxgb4: only call the cq comp_handler when the cq is armed iw_cxgb4: Fix possible circular dependency locking warning RDMA/bnxt_re: report vlan_id and sl in qp1 recv completion IB/core: Only maintain real QPs in the security lists IB/ocrdma_hw: remove unnecessary code in ocrdma_mbx_dealloc_lkey RDMA/core: Make function rdma_copy_addr return void RDMA/vmw_pvrdma: Add shared receive queue support RDMA/core: avoid uninitialized variable warning in create_udata RDMA/bnxt_re: synchronize poll_cq and req_notify_cq verbs RDMA/bnxt_re: Flush CQ notification Work Queue before destroying QP RDMA/bnxt_re: Set QP state in case of response completion errors RDMA/bnxt_re: Add memory barriers when processing CQ/EQ entries ... | |||
