[RFC] [PATCH 1/8] inode_diet: Replace inode.u.generic_ip with inode.i_private

From: Theodore Tso
Date: Mon Jun 19 2006 - 11:30:52 EST

The filesystem or device-specific pointer in the inode is inside a
union, which is pretty pointless given that all 30+ users of this
field have been using the void pointer. Get rid of the union and
rename it to i_private, with a comment to explain who is allowed to
use the void pointer. This is just a cleanup, but it allows us to
reuse the union 'u' for something something where the union will
actually be used.
