[patch 094/178] samples/vfio-mdev/mdpy: use remap_vmalloc_range

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: Christoph Hellwig <hch@xxxxxx>
Subject: samples/vfio-mdev/mdpy: use remap_vmalloc_range

Patch series "remap_vmalloc_range cleanups".

This series removes an open coded instance of remap_vmalloc_range and
removes the unused remap_vmalloc_range_partial export.


This patch (of 2):

Use remap_vmalloc_range instead of open coding it using
remap_vmalloc_range_partial.
