That got stamped out. swapon will fail if the file isn't fully instantiated on disk:
static int setup_swap_extents(struct swap_info_struct *sis) { ... block = bmap(inode, probe_block + block_in_page); if (block == 0) goto bad_bmap; ...
bad_bmap: printk(KERN_ERR "swapon: swapfile has holes\n"); ret = -EINVAL; } - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
