Off the top of my head, lazy unmounting comes to mind. Think of this: mount foobar /mnt -o loop; cd /mnt; umount /mnt; Currently, this leaves /dev/loop0 assigned, either chewing up loop places or needlessy exposing objects meant to be rather not accessible. (Think cryptoloop devices -- and pam_mount.) BTW, such a flag would also really be useful for dm(-crypt). - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
