[PATCH] ext4: update mtime in ext4_punch_hole even if no blocks are released

by Lukas Czerner

Currently in ext4_punch_hole we're going to skip the mtime update if there are no actual blocks to release. However we've actually modified the file by zeroing the partial block so the mtime should be updated. Moreover the sync and datasync handling is skipped as well, which is also wrong. Fix it.

[PATCH v2 03/12] arm: dts: mt7623: fix invalid memory node being generated

by sean.wang＠mediatek.com

From: Sean Wang <sean.wang(a)mediatek.com> Below two wrong nodes in existing DTS files would cause a fail boot since in fact the address 0 is not the correct place the memory device locates at. memory { device_type = "memory"; reg = <0x0 0x0 0x0 0x0>; }; memory@80000000 { reg = <0x0 0x80000000 0x0 0x40000000>; }; In order to avoid having a memory node starting at address 0, we can't include file skeleton64.dtsi and instead need to explicitly manually define a few of properties the DTS relies on such as #address-cells and #size-cells in root node and device_type in the node memory@80000000.

[PATCH 3/3] x86/mm: disable ioremap free page handling on x86-PAE

by Toshi Kani

ioremap() supports pmd mappings on x86-PAE. However, kernel's pmd tables are not shared among processes on x86-PAE. Therefore, any update to sync'd pmd entries need re-syncing. Freeing a pte page also leads to a vmalloc fault and hits the BUG_ON in vmalloc_sync_one(). Disable free page handling on x86-PAE. pud_free_pmd_page() and pmd_free_pte_page() simply return 0 if a given pud/pmd entry is present. This assures that ioremap() does not update sync'd pmd entries at the cost of falling back to pte mappings.

[PATCH v9 0/9] dax: fix dma vs truncate/hole-punch

by Dan Williams

Changes since v8 [1]: * Rebase on v4.17-rc2 * Fix get_user_pages_fast() for ZONE_DEVICE pages to revalidate the pte, pmd, pud after taking references (Jan) * Kill dax_layout_lock(). With get_user_pages_fast() for ZONE_DEVICE fixed we can then rely on the {pte,pmd}_lock to synchronize dax_layout_busy_page() vs new page references (Jan) * Hold the iolock over repeated invocations of dax_layout_busy_page() to enable truncate/hole-punch to make forward progress in the presence of a constant stream of new direct-I/O requests (Jan). [1]: https://lists.01.org/pipermail/linux-nvdimm/2018-March/015058.html --- Background: get_user_pages() in the filesystem pins file backed memory pages for access by devices performing dma. However, it only pins the memory pages not the page-to-file offset association. If a file is truncated the pages are mapped out of the file and dma may continue indefinitely into a page that is owned by a device driver. This breaks coherency of the file vs dma, but the assumption is that if userspace wants the file-space truncated it does not matter what data is inbound from the device, it is not relevant anymore. The only expectation is that dma can safely continue while the filesystem reallocates the block(s). Problem: This expectation that dma can safely continue while the filesystem changes the block map is broken by dax. With dax the target dma page *is* the filesystem block. The model of leaving the page pinned for dma, but truncating the file block out of the file, means that the filesytem is free to reallocate a block under active dma to another file and now the expected data-incoherency situation has turned into active data-corruption. Solution: Defer all filesystem operations (fallocate(), truncate()) on a dax mode file while any page/block in the file is under active dma. This solution assumes that dma is transient. Cases where dma operations are known to not be transient, like RDMA, have been explicitly disabled via commits like 5f1d43de5416 "IB/core: disable memory registration of filesystem-dax vmas". The dax_layout_busy_page() routine is called by filesystems with a lock held against mm faults (i_mmap_lock) to find pinned / busy dax pages. The process of looking up a busy page invalidates all mappings to trigger any subsequent get_user_pages() to block on i_mmap_lock. The filesystem continues to call dax_layout_busy_page() until it finally returns no more active pages. This approach assumes that the page pinning is transient, if that assumption is violated the system would have likely hung from the uncompleted I/O. --- Dan Williams (9): dax, dm: introduce ->fs_{claim,release}() dax_device infrastructure mm, dax: enable filesystems to trigger dev_pagemap ->page_free callbacks memremap: split devm_memremap_pages() and memremap() infrastructure mm, dev_pagemap: introduce CONFIG_DEV_PAGEMAP_OPS mm: fix __gup_device_huge vs unmap mm, fs, dax: handle layout changes to pinned dax mappings xfs: prepare xfs_break_layouts() to be called with XFS_MMAPLOCK_EXCL xfs: prepare xfs_break_layouts() for another layout type xfs, dax: introduce xfs_break_dax_layouts() drivers/dax/super.c | 99 ++++++++++++++++++++-- drivers/md/dm.c | 57 +++++++++++++ drivers/nvdimm/pmem.c | 3 - fs/Kconfig | 2 fs/dax.c | 97 +++++++++++++++++++++ fs/ext2/super.c | 6 + fs/ext4/super.c | 6 + fs/xfs/xfs_file.c | 72 +++++++++++++++- fs/xfs/xfs_inode.h | 16 ++++ fs/xfs/xfs_ioctl.c | 8 -- fs/xfs/xfs_iops.c | 16 ++-- fs/xfs/xfs_pnfs.c | 16 ++-- fs/xfs/xfs_pnfs.h | 6 + fs/xfs/xfs_super.c | 20 ++-- include/linux/dax.h | 71 +++++++++++++++- include/linux/memremap.h | 25 ++---- include/linux/mm.h | 71 ++++++++++++---- kernel/Makefile | 3 - kernel/iomem.c | 167 +++++++++++++++++++++++++++++++++++++ kernel/memremap.c | 208 ++++++---------------------------------------- mm/Kconfig | 5 + mm/gup.c | 37 ++++++-- mm/hmm.c | 13 --- mm/swap.c | 3 - 24 files changed, 730 insertions(+), 297 deletions(-) create mode 100644 kernel/iomem.c

Applied "spi: pxa2xx: Allow 64-bit DMA" to the spi tree

by Mark Brown

The patch spi: pxa2xx: Allow 64-bit DMA has been applied to the spi tree at https://git.kernel.org/pub/scm/linux/kernel/git/broonie/spi.git All being well this means that it will be integrated into the linux-next tree (usually sometime in the next 24 hours) and sent to Linus during the next merge window (or sooner if it is a bug fix), however if problems are discovered then the patch may be dropped or reverted. You may get further e-mails resulting from automated or manual testing and review of the tree, please engage with people reporting problems and send followup patches addressing any issues that are reported if needed. If any updates are required or you are submitting further changes they should be sent as incremental updates against current git, existing patches will not be replaced. Please add any relevant lists and maintainers to the CCs when replying to this mail.

[PATCH v2] KVM: vmx: update sec exec controls for UMIP iff emulating UMIP

by Sean Christopherson

Update SECONDARY_EXEC_DESC for UMIP emulation if and only UMIP is actually being emulated. Skipping the VMCS update eliminates unnecessary VMREAD/VMWRITE when UMIP is supported in hardware, and on platforms that don't have SECONDARY_VM_EXEC_CONTROL. The latter case resolves a bug where KVM would fill the kernel log with warnings due to failed VMWRITEs on older platforms.

[PATCH 0/6] virtio-console: spec compliance fixes

by Michael S. Tsirkin

Turns out virtio console tries to take a buffer out of an active vq. Works by sheer luck, and is explicitly forbidden by spec. And while going over it I saw that error handling is also broken - failure is easy to trigger if I force allocations to fail. Lightly tested. Michael S. Tsirkin (6): virtio_console: don't tie bufs to a vq virtio: add ability to iterate over vqs virtio_console: free buffers after reset virtio_console: drop custom control queue cleanup virtio_console: move removal code virtio_console: reset on out of memory drivers/char/virtio_console.c | 155 ++++++++++++++++++++---------------------- include/linux/virtio.h | 3 + 2 files changed, 75 insertions(+), 83 deletions(-) -- MST
