Stop the HOSTFS filesystem from using iget() and read_inode(). Provide
hostfs_iget(), and call that instead of iget(). hostfs_iget() then uses
iget_locked() directly and returns a proper error code instead of an inode in
the event of an error.
hostfs_fill_sb_common() returns any error incurred

Remove the old iget() call and the read_inode() superblock operation it uses
as these are really obsolete, and the use of read_inode() does not produce
proper error handling (no distinction between ENOMEM and EIO when marking
an inode bad).
Furthermore, this removes the temptation to use iget()

I don't want to jump the gun on the analysis but it just might
be the packet sharing fixes Herbert put in a short time ago.
What you could do is go back to say rc2 and see if you still get
the panics, then bisect from there to narrow it down.
If rc2 still gives the panic, it's

the result?
