Hello,
Linux-v4.10 has a commit 48f7df329474 2016-02-18 mm: fix regression in remap_file_pages() emulation and it contains a small test program where remap_file_pages() will split a region into two VMAs.
Linux-v6.1-rc1 remap_file_pages() doesn't pass that old test. I tried investigation, but I am not good in this tech field. I could only find there may be related to the commit 763ecb035029 2022-09-26 mm: remove the vma linked list but I am not sure. How can we make the old test pass? "Don't use remap_file_pages()" or "Ignore such old test" is not an option.
