[patch 113/128] mm: switch the test_vmalloc module to use __vmalloc_node

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

 



From: Christoph Hellwig <hch@xxxxxx>
Subject: mm: switch the test_vmalloc module to use __vmalloc_node

No need to export the very low-level __vmalloc_node_range when the test
module can use a slightly higher level variant.

[akpm@xxxxxxxxxxxxxxxxxxxx: add missing `node' arg]
[akpm@xxxxxxxxxxxxxxxxxxxx: fix riscv nommu build]
