There are two unrelated changes to the calling convention for ->huge_fault. I've bundled them together to help people notice the change. The first is to improve scalability of DAX page faults by allowing them to be handled under the VMA lock. The second is to remove enum page_entry_size since it's really unnecessary. The changelogs and documentation updates hopefully work to that end. I vaguely contemplated introducing PTE_ORDER to replace use of the bare '0' order. I'll happily do it if anyone feels strongly about it. v2: - Split into three patches - Use PAGE_SHIFT instead of PTE_SHIFT to fix build errors on hexagon & csky Matthew Wilcox (Oracle) (3): mm: Move PMD_ORDER to pgtable.h mm: Allow ->huge_fault() to be called without the mmap_lock held mm: Remove enum page_entry_size Documentation/filesystems/locking.rst | 36 +++++++++++++++++---------- Documentation/filesystems/porting.rst | 11 ++++++++ drivers/dax/device.c | 22 ++++++---------- fs/dax.c | 33 ++++++------------------ fs/erofs/data.c | 6 ++--- fs/ext2/file.c | 2 +- fs/ext4/file.c | 11 ++++---- fs/fuse/dax.c | 20 +++++++-------- fs/xfs/xfs_file.c | 24 +++++++++--------- fs/xfs/xfs_trace.h | 22 ++++++++-------- include/linux/dax.h | 4 +-- include/linux/mm.h | 10 +------- include/linux/pgtable.h | 3 +++ mm/memory.c | 30 +++++----------------- 14 files changed, 102 insertions(+), 132 deletions(-) -- 2.40.1
