Re: [next] mips-mt.c:233:19: error: conflicting types for 'mt_init'

Hi Liam,

Would you consider renaming maple tree's "mt_init()" function to
maple_tree_init() or mtree_init() or something that does not
conflict with the mt_init() function in arch/mips/ so that
these build errors don't happen?

thanks.
