From: Matthew Wilcox <willy@xxxxxxxxxxxxx>
Subject: cramfs: convert to use vmf_insert_mixed
Patch series "Push the vm_fault_t conversion further".
This patch series reaps some of the benefits of the vm_fault_t work that
Souptick has been diligently plugging away at by converting insert_pfn()
to return a vm_fault_t.
Eventually, we'll be able to do the same thing to insert_page(), but
there's more work to be done converting all current callers of
vm_insert_page() to vmf_insert_page(), and this patch series provides a
nice clean-up.
This patch (of 10):
cramfs is the only remaining user of vm_insert_mixed; convert it.
