RE: BUG REPORT - IDR wraps around at 30-bits - works very bad with NFSD/SCTP

[Shyam Kaushik]

It was just more time from me on this:-) But anyways since you wanted I
tried.

I tested 3.10.6-031006-generic & it works perfect in there!

[  832.513688] Processing for min_stateid[0]
[  832.513701] Allocated new_stid[0]
[  832.513703] Dumping entries in IDR
[  832.513705]  IDR Actual ID[0] == Expected Value[0]
[  832.513710]
[  832.513710] Processing for min_stateid[1073741823]

[  832.513714] Dumping entries in IDR
[  832.513729]  IDR Actual ID[1073741823] == Expected Value[1073741823]
[  832.513731]

[  832.513779]  IDR Actual ID[2147483647] == Expected Value[2147483647]

Any chances of backporting some parts of fix to <3.9 kernels?

Thanks.

There shouldn't be anything in 3.10 preventing you from building and
testing it out, is there?  Or do you have something that restricts you
to specific kernel versions?

thanks,
