I get "KERNEL_VERSION" is not defined and "LINUX_VERSION_CODE" is not defined but don't past error: missing binary operator before token "(" Have tried with different kernel versions 2.6.24-r2, 2.6.27-r7 and 2.6.28
I've changed the patch iscsitarget-0.4.17+linux-2.6.28.patch and removed all IF statements. After that iscsitarget-0.4.17 compiled fine. Thanks to CGretski. May be it'll be better to check the kernel version inside the ebuild and apply patch only for 2.6.28 kernel.
Looks like this is fixed now.
