Little patch here (it's from Linus) will allow __d_path to take a NULL vfsmount pointer.
Ok, thanks, I'll try that :)
Still in the same area, I need to get the dentry in my module from a path, so path_loohup() seems to be appropriate. But when I try to insmod the module, it says the symbol is path_lookup() not defined (but it is present in System.map).
2 "bonus questions" :
- what is the difference between /proc/ksyms and System.map
- what does the macro FASTCALL means ? (I've seen its def but dont understand it).
Thanks for the help,
