I have a little bit changed the command line option to: --direct-io[=on|off] where the default is "on", so you can use: losetup -f --direct-io file.img to enable direct-io, to disable you have to use: losetup --direct-io=off /dev/loop0 I guess the most common usage will be to enable direct I/O :-) https://github.com/karelzak/util-linux/commit/f98d9641a371421640a8f1cfe497030758f86dca Karel -- Karel Zak <kzak@xxxxxxxxxx> http://karelzak.blogspot.com -- To unsubscribe from this list: send the line "unsubscribe util-linux" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
