[patch 112/128] mm: remove __vmalloc_node_flags_caller

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

 



From: Christoph Hellwig <hch@xxxxxx>
Subject: mm: remove __vmalloc_node_flags_caller

Just use __vmalloc_node instead which gets and extra argument.  To be able
to to use __vmalloc_node in all caller make it available outside of
vmalloc and implement it in nommu.c.
