Interesting. Perhaps we can just delete it.
As Dewey reported later, procfs_macros.h is used in the RTAI backend of
RTAPI, and deleting it breaks the RTAI build unless we turn off our
/proc code at the same time.
I'm testing 2.8 on Wheezy with the 3.4-9-rtai-686-pae kernel from our
package archive.
There are a bunch of things in /proc/rtapi that seem useful, that use
procfs_macros.h. Unfortunately reading from any of them produces
garbage. Writing to /proc/rtapi/debug works fine and does the expected
thing (rtapi messages start showing up in the kernel log).
This is representative:
~~~
$ cat /proc/rtapi/status
ssage level = 5
975 nSec
����
����
~~~
It seems like `seq_file` may be a better way for us to supply the
contents of our files in /proc? It's part of the mainline kernel.
