Message-ID: <1138763255.3938.27.camel@localhost.localdomain> (raw)

Hi KUROSAWA,
I tried to use the controller but having some problems.
- Created class a,
- set guarantee to 50(with parent having 100, i expected class a to get
50% of memory in the system).
- moved my shell to class a.
- Issued a make in the kernel tree.
It consistently fails with
-----------
make: getcwd: : Cannot allocate memory
Makefile:313: /scripts/Kbuild.include: No such file or directory
Makefile:532: /arch/i386/Makefile: No such file or directory
Can't open perl script "/scripts/setlocalversion": No such file or
directory
make: *** No rule to make target `/arch/i386/Makefile'. Stop.
-----------
Note that the compilation succeeds if I move my shell to the default
class.
I got a oops too:

Note: "if (put_page_testzero(page)) {" is line 1074 in my source tree
Also, I do not see a mem= line in the stats file for the default class.
