Re: [RFC PATCH v1 4/8] zram: destroy all devices on error recoverypath in zram_init()

[Dan Carpenter]

Everyone stop putting RFC on their bugfixes!  :P  No one wants to
pre-review patches.

This is a real bug but the fix isn't right.  The object causing the
failure has only been partially set up.  And in some cases it has
been partially cleaned up, for example we could end up releasing
->queue twice.

The better way is to make create_device() clean up after itself
completely instead of only partly and sometimes.
