man insmod:
INSMOD(8) insmod INSMOD(8)
NAME
insmod - Simple program to insert a module into the Linux Kernel
SYNOPSIS
insmod [filename] [module options...]
DESCRIPTION
insmod is a trivial program to insert a module into the kernel. Most users will want to use modprobe(8) instead,
which is more clever and can handle module dependencies.
Only the most general of error messages are reported: as the work of trying to link the module is now done inside
the kernel, the dmesg usually gives more information about errors.

insmod 加载模块，需要指定完整的路径和模块名字。
说明：Linux有许多功能是通过模块的方式，在需要时才载入kernel。如此可使kernel较为精简，进而提高效率，以及保有较大的弹性。这类可载入的模块，通常是设备驱动程序。
