Subject: mmap: Pass through vmi iterator to __split_vma()
X-Git-Url: https://www.infradead.org/git/?a=commitdiff_plain;h=9490c4ddc124f6e6fd9124ee11d21473ffd0cd18;p=users%2Fjedix%2Flinux-maple.git

mmap: Pass through vmi iterator to __split_vma()

Use the vma iterator so that the iterator can be invalidated or updated
to avoid each caller doing so.
