There was a problem hiding this comment.
Is this a cherry-pick of ebb985d ? If so, can you please redo this Pull request by using -x flag to git cherry-pick -x so that git includes the "Cherry Picked From" comment in the commit message? This helps up keep track of commits in the future.
1) Race condition: Do not add private contexts to active list. Private contexts are only visible to the user. 2) Recycled contexts: Destroyed contexts are put on an idle list until finalize, continuous context creation will lead to oom condition. Instead, check if context from idle list meets new context requirements and reuse it. Co-authored with: Artem Y. Polyakov <[email protected]>, Manjunath Gorentla Venkata <[email protected]> Signed-off-by: Tomislav Janjusic <[email protected]> (cherry picked from commit bd7cdf7)
