However I cannot find any ubifs functions to form the above loop, so
ubifs should be safe for now.

  Yeah, me neither but I also failed to find a place where
ubifs_evict_inode() truncates inode space when deleting the inode... Artem?

We do call 'truncate_inode_pages()':

static void ubifs_evict_inode(struct inode *inode)
{
	...

        truncate_inode_pages(&inode->i_data, 0);

        ...
}

  Well, but that just removes pages from page cache. You should somewhere
also free allocated blocks and free the inode... And I'm sure you do,
otherwise you would pretty quickly notice that file deletion does not work
:) Just I could not find which function does it.
