Hello,
I googled but found nothing about the usage of the kern_* functions
(kern_open, kern_close, kern_pwritev, kern_preadv) that are located in
vfs_syscalls.c
When I use kern_open to open a file within the kernel, I get an error.
When I use the normal vn_open function instead, all works well.
So my question is which functions are recommended by you kernel-hackers
for use within kernelspace?
And here a second question: Is it possible to open/use the console driver in
kernelspace within the functions mentioned above?
If not, can you give me some pointers on where I can find this information!
Regards,
Marc
