hi ,<br><br>let me explain myself :<br> for example , open syscall calls sys_open then do_sys_open so<br>like: do_sys_open -> do_filp_open -> link_path_walk -> so on.<br>so while the cpu is executing the link_path_walk , is there any procedure in kernel to check for the interrupt vector number which caused it to be invoked?<br>
i mean like one of my friends said that when kernel is about to restart a syscall then it raises signal -ERESTARTSYS signal for signal handler. but i think it is for<br>something went wrong and kernel wanna start the syscall again. but in between a syscall routine is it possible to get vector number (i repeat ,sorry) ??<br>
<br>thanks in advance for help<br clear="all"><br>-- <br>........................<div><i>MOHIT VERMA</i></div><br>
