[Starlingx-discuss] Opinion wanted on STX 2.0 kernel memory leak bug 1836638

[Saul Wold]

Jim:

Great work on tracking down these issues, I am curious are they 
addressed in the newer 3.10 series from CentOS or only from other 
upstream sources? If they are from other uptream sources, has it been 
reported to CentOS/Redhat? More curious than anything else, not a 
requirement.

I do agree that we should make the changes to both kernel.

Sau!
