Thanks for your reply. But more details are appreciated. Actually I checked linkage.h before I sent last email. Looks like "fastcall" is used to direct the compiler to put the first 3 parameters into registers instead of stack. But I just don't understand why that causes "general protection fault". I am writing a new file system on Linux platform. So I thought this is the right email list where I can discuss Linux kernel developing questions. Is this email list only used to post patches and report bugs? If so, I will stay away. -x On 1/24/07, Oleg Verych <olecom@flower.upol.cz> wrote: > > On 2007-01-24, Xin Zhao wrote: > > Archived-At: <http://permalink.gmane.org/gmane.linux.kernel/485775> > > Hallo. > > > I just successfully called do_path_lookup() in my kernel module.
