While writing DKMS support for the SCST and iSCST-SCST kernel modules, I ran into a (common) problem with regard to out-of-tree build detection. A common method to detect out-of-tree building is by using the KERNELRELEASE variable. The usage of this variable poses a problem when using DKMS. DKMS itself uses the KERNELRELEASE variable to specify the kernel for which the driver to build. A suggested alternative would to use the PATCHLEVEL variable as part of the detection mechanism instead. I attached a patch reflecting this suggested change. git-svn-id: http://svn.code.sf.net/p/scst/svn/trunk@720 d57e44dd-8a1f-0410-8b47-8ef2f437770f
