status of patches ( raid5 multiple threads )

status of patches ( raid5 multiple threads )

[vincent Ferrer]

Hi Shaohua  (and linux-raid maintainers),

Interested in knowing status of patches  "raid5  create multiple threads "
http://www.spinics.net/lists/raid/msg39978.html

Specifically want to know if it is available in any of the latest
kernel releases 3.x ?

Or otherwise when are these patches expected to get merged into linux
kernel tree.

Appreciate great work.

Thanks & regards
vincy

I don't plan to submit them for 3.7, though I might for 3.8 if I get a change
to give them a proper review.

Hi  Neil / Shaohua,

Did the patches for  "raid5  create multiple threads" got
reviewed/merged into  3.8 kernel ?  Or otherwise what is the plan and
current state of multi-thread raid5 support in latest linux kernels ?

Appreciate your answers and great work.

No, not in 3.8.  I really should spend some time reviewing that code, but
I've had a very busy summer...

Have you (or anyone else) tested them?  Can you report anything positive or
negative?  Having someone other than the author say "this helped a lot" would
be a very strong motivator for me....

Have'nt tested/tried  yet. Which kernel version these patches can work with ?

"the latest".

They are in linux-next.  That might be the easiest place to try.

Hi Neil
I may be able to test it depending how compatible/portable patches are
with kernel  version 3.4.27.
Can you please give me rough estimate that how much effort it can be
to back port raid5 patches to  3.4.27 kernel

thanks !

I think there has probably been too much change from 3.4 to 3.7 for that to
be a really useful exercise.   Thanks anyway.
