I used do { if (inode_has_buffers(inode)) { printstate(); } kmem_cache_free.... } while (0)

and machine complained very loudly during boot...

test12-pre3, NULL in list_del, destroy_inode as above, UP, 2.95.2

So I thought that adding fsync_inode_buffers() added into iput() just below
atomic_dec_and_lock(&inode->i_count...) would be good idea. It is not, bug
was still trigerred. So there are oopses... I removed disassembled code,
as it is same for all oopses (as my printstate dumps itself).

Before fsync_inode_buffers() it was almost same, there were also traces
through sys_close() in additon to this. But maybe that I just did not
trigger this code path during testing.

I think that buffer_insert_inode_queue and __remove_inode_queue should
also do iget() and iput(), but maybe I'm wrong.

And I have no idea why fsync_inode_buffers() does not work. I thought that
inode should not have any buffers attached after this function returns if
inode use count was zero... Maybe it is a bit complicated when inode
is going to cease...
