Subject: Question about list_sort() RCU version.
Date: Tue, 16 Jun 2020 20:17:56 +0000	[thread overview]
Message-ID: <BYAPR04MB4965874567CDA672B704ABCC869D0@BYAPR04MB4965.namprd04.prod.outlook.com> (raw)

Hi RCU maintainers and experts,

I'm working on a linux kernel upstream project which is in the tree. 
With the POC I can already see that significant performance improvement 
with RCU in the fast path which are replacing rw semaphore, but not 
having list_sort() rcu variant is blocking the developement and getting 
code upstream.

I was not able to find the such helper implemented for the RCU flavor of 
list.

Can someone provide information about :-

1. Is there any plan to have list_sort_rcu() ? if so when can we expect
    that ? (Also how can I help ?)

2. In case there is no plan what are design considerations if someone
    wants to implement the code and submit it upstream ?
    (Also how can I help here ?

Regards,
-CK
