Subject: v6.1-rc1, remap_file_pages() and vma linked list?
Date: Tue, 25 Oct 2022 16:09:19 +0900 [thread overview]
Message-ID: <29344.1666681759@jrobl> (raw)
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.
