Subject: [PATCH] unpaged: copy_page_range vma
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=0b0db14c536debd92328819fe6c51a49717e8440;p=GitHub%2Fexynos8895%2Fandroid_kernel_samsung_universal8895.git

[PATCH] unpaged: copy_page_range vma

For copy_one_pte's print_bad_pte to show the task correctly (instead of
"???"), dup_mmap must pass down parent vma rather than child vma.
