<P>I am trying to trap when the kernel schedules a process because it has performed a page fault that is not directly accesable. Any one has got any idea where and how this is done? </P>
<P>To understand what is happing I placed a function call that contains a printk in the "do_page_fault" function found in the fault.c file. Strangely enough this function is never being called and i am 100% sure it must be called as it is just behind the good_area label. As a test to generate a page fault i am loading a big file and reading characters. An other test is mallocing a bif area (1024*1024*512) and writing in all of it.</P>
<P>Does UML make use of this inline function and of the entry.S file or does it replace them with something else that makes UML work? </P>
<P>Thanks in advance. </P>
