Hi to all,
I am running 32bit application on 64bit kernel i.e my driver compiled on
64bit.
In my driver I used rtdm_fd_is_compat(), to know user land request came
from 32-bit or 64bit app.
My doubt is what it will return if both the driver & app are different?
Regards,
Manikanta

rtdm_fd_is_compat() returns true when the current request to the 64bit
kernel originates from a 32bit app.
