Changes since v1 [1]: 1/ Fix the transparent_hugepage_enabled() rewrite to be functionally equivalent to the old state (Ross) 2/ Add a note as to why we are including fs.h in huge_mm.h so that we remember to clean this up if vma_is_dax() is ever moved, or we add a VM_* flag for this case. (prompted by Kirill's feedback). 3/ Add some ack and review tags. [1]: https://www.spinics.net/lists/linux-mm/msg128852.html --- Hi Andrew, Please consider taking these 2 patches for 4.13. I spent some time debugging why a user's device-dax configuration was always failing and it turned out that their thp policy was set to 'never'. DAX should be exempt from the policy since it is statically allocated and does not suffer from any of the potentially negative side effects of thp. More details in patch 2. --- Dan Williams (2): mm: improve readability of transparent_hugepage_enabled() mm: always enable thp for dax mappings include/linux/dax.h | 5 ----- include/linux/fs.h | 6 ++++++ include/linux/huge_mm.h | 37 ++++++++++++++++++++++++++----------- 3 files changed, 32 insertions(+), 16 deletions(-)
