Linux块设备驱动分析与模拟实现

  2 # Makefile for the kernel block device drivers.

  4 # Note! Dependencies are done automagically by 'make dep', which also
  5 # removes any old dependencies. DON'T put your own dependencies here
  6 # unless it's something special (ie not a .c file).
  7 #
  8 # Note 2! The CFLAGS definition is now inherited from the
  9 # parent makefile.
