[minor fix] radixtree: regulate tag get return value

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

 



Andrew, this small patch makes the radixtree tester program from
        http://www.zip.com.au/~akpm/linux/patches/stuff/rtth.tar.gz
run OK, with the latest radix tree code in linux-2.6.17-rc5-mm2.

It regulates the return value to 0/1 for functions
radix_tree_tag_get() and radix_tree_tagged().
