I was just hoping somebody had a better idea, like a way to add a new
format specifier to printk without losing gcc type checking :-)
It's been discussed before. Some of the solutions discussed:
- Add something like PRI_RES which can be concatenated into a printk.
Ugly.
- Patch gcc to allow user-definable types. I think OpenBSD has a
patch
for this. Then we have to get that patch propagated to all the
people who compile the kernel. Unappetising.
- Disable gcc's printk checking, teach sparse to typecheck printk.
Most people don't run sparse yet.
How does gcc deal with glibc extension to allow people to add their
own specifiers?
