Subject: [PATCH 0/6] mremap: move_vma() fixes
Date: Tue, 13 Oct 2020 02:34:10 +0100 [thread overview]
Message-ID: <20201013013416.390574-1-dima@arista.com> (raw)
1 - seems to be historical issue on a rarely taken path
2,3 - fixes related to the new mremap() flag
5 - dax device/hugetlbfs possible issue
4,6 - refactoring
As those seems to be actual issues, sending this during the merge-window.
(Changes to architecture code are in the 6 patch, but Cc'ing
maintainers on cover for the context, I hope it's fine).
