various tests for 3.0 rt3

various tests for 3.0 rt3

[Jordi Pujol]

Hello,

Testing 3.0 rt3 with overlayfs, aufs, tuxonice, nvidia drivers,

to compile the NVIDIA propietary driver, kernel has to export as non-GPL the 
following symbols,

__rt_mutex_init
migrate_enable
migrate_disable

tuxonice suspends and resumes to S1 successfully, (have not tested S3, by 
now),
but can not hibernate to disk, the system is locked just when suspend to disk 
begins to show the message "Doing atomic copy/restore."

aufs works without any modification

overlayfs works also

also, the rt3 patch has needed a bit of modification for a succesful 
application, there is a conflict with another patch:
candidate/0020-x86-mtrr-lock-stop-machine-during-MTRR-rendezvous-se.patch

***

 }

Thanks,

Does anyone have a patch for this? Previously it was the nvidia
drivers which needed to be patched, but it seems in this case the
patch needs to be kernel-side?

making a patch is easy, license is the problem, the symbols are exported as 
GPL therefore a non-GPL module has not rights to use it,

Here is a discussion about that,
