actual assertion in destroy_inode() which is a little bogus.

But the wierd thing is that this BUG only hit a single time, after three hours of intensive testing. If my theory is
right, the BUG should hit every time. Will investigate further...

It appears that this problem is not fixed.

My destroy_inode() is now

static void destroy_inode(struct inode *inode)

{
        if (!list_empty(&inode->i_dirty_buffers)) {
                printk("&inode->i_dirty_buffers=0x%p\n", &inode->i_dirty_buffers);
                printk("next=0x%p\n", inode->i_dirty_buffers.next);
                printk("prev=0x%p\n", inode->i_dirty_buffers.prev);
                BUG();
        }
        kmem_cache_free(inode_cachep, (inode));
}

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

and machine complained very loudly during boot...

This is 2.4.0-test11-pre3 + list_del patch + sct's inode patch (buffer.c, inode.c). x86 dual processor. gcc 2.91.66. I rediffed my tree. No rogue patches.

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...
