Error handling code following a kmalloc should free the allocated data.

Inode cache and inode operations. We also include routines to incorporate metadata structures returned by the MDS into the client cache, and some helpers to deal with file capabilities and metadata leases. The bulk of that work is done by fill_inode() and fill_trace(). Signed-off-by: NSage Weil <sage@newdream.net>
