Hello XLOV,
Its better to use filp_open in the file operation structure to implement the functionality thats the best way(as mr. gopu had said) . Those are static functions used by kernel which will be linked when you insert the module .. So no problem .

Subject: Which types of functions are exported by kernel source?
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.
