[PATCH v2 0/2] ublk: decouple server threads from hctxs

Posted by Uday Shankar 10 months ago

This patch set aims to allow ublk server threads to better balance load
amongst themselves by decoupling server threads from ublk queues/hctxs,
so that multiple threads can service I/Os from a single hctx.

Changes in v2:
- Remove changes split into other patches
- To ease error handling/synchronization, associate each I/O (instead of
  each queue) to the last task that issues a FETCH_REQ against it. Only
  that task is allowed to operate on the I/O.
- Link to v1: https://lore.kernel.org/r/20241002224437.3088981-1-ushankar@purestorage.com

Uday Shankar (2):
      ublk: properly serialize all FETCH_REQs
      ublk: require unique task per io instead of unique task per hctx
