The -rt patch triggers a lockdep warning for serial drivers if tty_flip_buffer_push() is called with uart_port->lock locked. This never shows up on UP kernels.
What about SMP kernels? linux-next?
As per Thomas Gleixner initial patch, it must break for SMP too. But we have tested it only for 3.10 stable merged with RT Kernel patchset..
Haven't tried it on linux-next..
This is neither tested nor compiled.
So I'm guessing you don't want it to be applied, if you can't take the time to at least test-build it, why should we?
{sigh}
:( ..
Actually I build tested it for few ARM platforms but not for others.. Now its build tested for all platforms that are modified here..
Lots of tty and serial changes have happened since -rc5 in linux-next, can you please rebase, and test, these against that tree and resend them if they are still needed?
I have rebased them over latest linux-next and they applied cleanly.. Haven't tested it though.. Will try that next week.
Sorry for the noise :(
