Modules are a different story: you can't call modules via the syscall table (because the global pointer will be wrong). This is actually a feature since it's almost always either wrong or illegal to install syscalls from a module. In fact, in newer kernels, the syscall table isn't exported to modules anymore. That's a good thing. Raj> BTW: I bought "ia-64 linux kernel design and implementation" Raj> book. It is very well wriiten. Thanks! --davidReceived on Fri May 30 10:48:57 2003
