( https://gerrit.osmocom.org/c/libosmocore/+/40489?usp=email ) Change subject: Allow io_uring_submit batching just ahead of poll/select ...................................................................... Patch Set 4: Code-Review-1 (6 comments) Patchset: PS4: Fine with having the extra envvar for now (I guess we'll want to remove it later on once we figure out this new approach is good). Marking -1 because the optimization to skip calling io_uring if not needed was not yet added. See comments attached.
