8 * We don't like to use these because they print to the dmesg console, which is
9 * spammy - we much prefer to be wired up to a userspace programm (e.g. via
10 * thread_with_file) and have it print the progress indicator.
11 *
12 * But some code is old and doesn't support that, or runs in a context where
13 * that's not yet practical (mount).
