*
|
||||
* rf_configure.c -- code related to configuring the raidframe system
|
||||
*
|
||||
* configuration is complicated by the fact that we want the same
|
||||
* driver to work both in the kernel and at user level. In the
|
||||
* kernel, we can't read the configuration file, so we configure
|
||||
* by running a user-level program that reads the config file,
|
||||
* creates a data structure describing the configuration and
|
||||
* passes it into the kernel via an ioctl. Since we want the config
|
||||
* code to be common between the two versions of the driver, we
|
||||
* configure using the same two-step process when running at
|
||||
* user level. Of course, at user level, the config structure is
|
||||
* passed directly to the config routine, rather than via ioctl.
|
||||
*
|
||||
* This file is not compiled into the kernel, so we have no
|
||||
* need for KERNEL ifdefs.
