Hello, While browsing linux source code what i found that if function is defined as asmlinkage long sys_open(const char * filename, int flags, int mode) then its not exported to kenrel and thus not seen in /proc/ksyms. But if function in kernel source is not defined with asmlinkage then it is exported to kernel and seen in /proc/ksyms. Is that correct?? regards, linux_lover. __________________________________ Do you Yahoo!? All your favorites on one personal page – Try My Yahoo! http://my.yahoo.com
