[PATCH 24/29] mm: remove __vmalloc_node_flags_caller

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

 



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.
