[PATCH v2 0/3] mm/memory: remove unused vmf_insert_mixed_mkwrite()

[Sang-Heon Jeon <ekffu200098@gmail.com>]

Hello,

Since commit 38607c62b34b ("fs/dax: properly refcount fs dax pages"),
vmf_insert_mixed_mkwrite() has no callers. This series removes it and
the mkwrite handling that only it used.

Patch 1 removes the function.

Patch 2 removes the mkwrite argument, which is then always false. It
also removes the unreachable code in insert_pfn().

Patch 3 merges __vm_insert_mixed() into vmf_insert_mixed().

No functional change.

---
Changes from v1 [1]
- Split into three patches for easier review
- Move the comment about -EBUSY handling above the check in
  __vm_insert_mixed()
