rifs-kernel3.5.x RIFS-SCHEDULER-3.5.x Offical 7 hours ago 7 hours ago 179 KB 6

kernel/exit.c: In function ‘__exit_signal’:
kernel/exit.c:148:32: error: ‘struct task_struct’ has no member named ‘se’
make[2]: *** [kernel/exit.o] Error 1
make[1]: *** [kernel] Error 2

My LCD monitor is out of work. I am just going to post the hotfix for it until I have got my monitor back.

Posted. Download it here: http://rifs-scheduler.googlecode.com/files/sched.h and replace the original one at /linux-3.5/include/linux/

[bug!]

with "RIFS-ES-SCHEDULER-3.5.x Hotfix For RIFS Offical Emergency" the kernel compiles without errors
but rsyslogd fails on boot (similar to https://code.google.com/p/rifs-sched...es/detail?id=2)

root@tux:/var/log# rsyslogd
Error during class init for object 'rsyslog runtime' - failing...
rsyslogd initializiation failed - global classes could not be initialized.
Did you do a "make install"?
Suggested action: run rsyslogd with -d -n options to see what exactly fails.
rsyslogd run failed with error 22 (see rsyslog.h or try http://www.rsyslog.com/e/-22 to learn what that number means)

I will start finding the reason of why rsyslogd failed(including my box, but I don't use rsyslogd at all) after few days(or even longer). In this month I am busy.

Some users reported that the RIFS kernel cannot be compiled with Tickless option.
Can anyone describes about this issues? I can compile the kernel with Tickless.

I'll see if I can find some time and try compiling the kernel with tickless

really would like to use RIFS on a laptop but tickless plays an important role

genkernel has been picky in the past where it failed with genkernel

whereas with normal "make" it DID compile cleanly

might be the same this time ... compiling manually with 1 thread now ...


edit:

will start completely from scratch and see if it works ...

Sorry, these days i am busy.
I have read your test and i have figured out the problem(I have to follow up the mainline kernel and copy the part of nohz handling. Thanks.
