Merge tag 'libnvdimm-fixes-4.19-rc8' of git://git.kernel.org/pub/scm/linux/kernel/git/nvdimm/nvdimm
Dan writes: "libnvdimm/dax 4.19-rc8 * Fix a livelock in dax_layout_busy_page() present since v4.18. The lockup triggers when truncating an actively mapped huge page out of a mapping pinned for direct-I/O. * Fix mprotect() clobbers of _PAGE_DEVMAP. Broken since v4.5 mprotect() clears this flag that is needed to communicate the liveness of device pages to the get_user_pages() path." * tag 'libnvdimm-fixes-4.19-rc8' of git://git.kernel.org/pub/scm/linux/kernel/git/nvdimm/nvdimm: mm: Preserve _PAGE_DEVMAP across mprotect() calls filesystem-dax: Fix dax_layout_busy_page() livelock
