This difference is precisely how we exposed a difference in behavior.

[PATCH v3 1/2] fs/sysctl: fix potential page fault while unregistering sysctl table

[PATCH v4 00/12] vfio, dax: prevent long term filesystem-dax pins and other fixes

by Dan Williams

The following series implements... Changes since v3 [1]: * Kill IS_DAX() in favor of explicit IS_FSDAX() and IS_DEVDAX() helpers. Jan noted, "having IS_DAX() and IS_FSDAX() doing almost the same, just not exactly the same, is IMHO a recipe for confusion", and I agree. A nice side effect of this elimination is a cleanup to remove occasions of "#ifdef CONFIG_FS_DAX" in C files, it is all moved to header files now. (Jan) --- The vfio interface, like RDMA, wants to setup long term (indefinite) pins of the pages backing an address range so that a guest or userspace driver can perform DMA to the with physical address. Given that this pinning may lead to filesystem operations deadlocking in the filesystem-dax case, the pinning request needs to be rejected. The longer term fix for vfio, RDMA, and any other long term pin user, is to provide a 'pin with lease' mechanism. Similar to the leases that are hold for pNFS RDMA layouts, this userspace lease gives the kernel a way to notify userspace that the block layout of the file is changing and the kernel is revoking access to pinned pages. Related to this change is the discovery that vma_is_fsdax() was causing device-dax inode detection to fail. That lead to series of fixes and cleanups to make sure that S_DAX is defined correctly in the CONFIG_FS_DAX=n + CONFIG_DEV_DAX=y case. --- Dan Williams (12): dax: fix vma_is_fsdax() helper dax: introduce IS_DEVDAX() and IS_FSDAX() ext2, dax: finish implementing dax_sem helpers ext2, dax: define ext2_dax_*() infrastructure in all cases ext4, dax: define ext4_dax_*() infrastructure in all cases ext2, dax: replace IS_DAX() with IS_FSDAX() ext4, dax: replace IS_DAX() with IS_FSDAX() xfs, dax: replace IS_DAX() with IS_FSDAX() mm, dax: replace IS_DAX() with IS_DEVDAX() or IS_FSDAX() fs, dax: kill IS_DAX() dax: fix S_DAX definition vfio: disable filesystem-dax page pinning drivers/vfio/vfio_iommu_type1.c | 18 ++++++++++++++-- fs/ext2/ext2.h | 6 +++++ fs/ext2/file.c | 19 +++++------------ fs/ext2/inode.c | 10 ++++----- fs/ext4/file.c | 18 +++++----------- fs/ext4/inode.c | 4 ++-- fs/ext4/ioctl.c | 2 +- fs/ext4/super.c | 2 +- fs/iomap.c | 2 +- fs/xfs/xfs_file.c | 14 ++++++------- fs/xfs/xfs_ioctl.c | 4 ++-- fs/xfs/xfs_iomap.c | 6 +++-- fs/xfs/xfs_reflink.c | 2 +- include/linux/dax.h | 12 ++++++++--- include/linux/fs.h | 43 ++++++++++++++++++++++++++++----------- mm/fadvise.c | 3 ++- mm/filemap.c | 4 ++-- mm/huge_memory.c | 4 +++- mm/madvise.c | 3 ++- 19 files changed, 102 insertions(+), 74 deletions(-)

Building an allmodconfig kernel fails horribly because of endian mismatch.

Patch "m32r: fix endianness constraints" has been added to the 4.14-stable tree

by gregkh＠linuxfoundation.org

This is a note to let you know that I've just added the patch titled m32r: fix endianness constraints to the 4.14-stable tree which can be found at: http://www.kernel.org/git/?p=linux/kernel/git/stable/stable-queue.git;a=sum… The filename of the patch is: m32r-fix-endianness-constraints.patch and it can be found in the queue-4.14 subdirectory. If you, or anyone else, feels it should not be added to the stable tree, please let <stable(a)vger.kernel.org> know about it. >From c95f121142a41c951fd62683a5574f2a7b37c573 Mon Sep 17 00:00:00 2001 From: Geert Uytterhoeven <geert(a)linux-m68k.org> Date: Wed, 15 Nov 2017 17:31:18 -0800 Subject: m32r: fix endianness constraints From: Geert Uytterhoeven <geert(a)linux-m68k.org> commit c95f121142a41c951fd62683a5574f2a7b37c573 upstream. The m32r Kconfig provides both CPU_BIG_ENDIAN and CPU_LITTLE_ENDIAN configuration options. As they are user-selectable and independent, this allows invalid configurations: - All m32r defconfigs build a big endian kernel, but CPU_BIG_ENDIAN is not set, causing compiler warnings like: include/linux/byteorder/big_endian.h:7:2: warning: #warning inconsistent configuration, needs CONFIG_CPU_BIG_ENDIAN [-Wcpp] #warning inconsistent configuration, needs CONFIG_CPU_BIG_ENDIAN ^ - Since commit 5bdfca6435b82944 ("m32r: define CPU_BIG_ENDIAN"), building an allmodconfig or allyesconfig enables both CONFIG_CPU_BIG_ENDIAN and CONFIG_CPU_LITTLE_ENDIAN. While this did get rid of the warning above, both options are obviously mutually exclusive. Fix this by making only CPU_LITTLE_ENDIAN configurable by the user, as before, and by making sure exactly one of CPU_BIG_ENDIAN and CPU_LITTLE_ENDIAN is always enabled.
