[PATCH 0/2] Support direct I/O read and write for memory allocated by dmabuf

[Lei Liu]

Use vm_insert_page to establish a mapping for the memory allocated
by dmabuf, thus supporting direct I/O read and write; and fix the
issue of incorrect memory statistics after mapping dmabuf memory.

Lei Liu (2):
  mm: dmabuf_direct_io: Support direct_io for memory allocated by dmabuf
  mm: dmabuf_direct_io: Fix memory statistics error for dmabuf allocated
    memory with direct_io support
