Subject: mm/mmap: Remove maple tree erase call in __vma_unlink_common
X-Git-Url: https://www.infradead.org/git/?a=commitdiff_plain;h=8ecb8766e2c8e706443d60f060c48c5136fa68d0;p=users%2Fjedix%2Flinux-maple.git

mm/mmap: Remove maple tree erase call in __vma_unlink_common

__vma_unlink_common is used when overwriting the next vma entry.  Maple
tree overwrites these entries on the store of the vma itself.
