[patch 100/162] radix tree test suite: fix build

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

 



From: Matthew Wilcox <willy@xxxxxxxxxxxxxxx>
Subject: radix tree test suite: fix build

Add an empty linux/init.h, and definitions for a few parts of the kernel
API either in use now, or to be used in the near future.  Start using the
common definitions in tools/include/linux, although more work needs to be
done here.
