Brian Behlendorf 51a727e90f Set cwd to '/' for the process executing insmod. ... Ricardo has pointed out that under Solaris the cwd is set to '/' during module load, while under Linux it is set to the callers cwd. To handle this cleanly I've reworked the module *_init()/_exit() macros so they call a *_setup()/_cleanup() function when any SPL dependent module is loaded or unloaded. This gives us a chance to perform any needed modification of the process, in this case changing the cwd. It also handily provides a way to avoid creating wrapper init()/exit() functions because the Solaris and Linux prototypes differ slightly. All dependent modules should now call the spl helper macros spl_module_{init,exit}() instead of the native linux versions. Unfortunately, it appears that under Linux there has been no consistent API in the kernel to set the cwd in a module. Because of this I have had to add more autoconf magic than I'd like. However, what I have done is correct and has been tested on RHEL5, SLES11, FC11, and CHAOS kernels. In addition, I have change the rootdir type from a 'void *' to the correct 'vnode_t *' type. And I've set rootdir to a non-NULL value.		2009-10-01 16:06:15 -07:00
