Subject: Re: [RFC][PATCH 00/10] On inode::i_count and the usage vs reference
 count issue

Usage counts are common and useful, so for now they should stay as-is
and if people can came up with a useful primitive for them we can
consider implementing it.

Trying to shoe-horn everything into refcount_t is a horrible idea.
