Patch proposes lockless FIFO MPSC queue for io_uring
A Linux kernel patch proposes adding a lockless FIFO queue to io_uring, with multiple producers and one consumer. The post also points to an original MPSC queue design from 2008.
A Linux kernel patch proposes adding a lockless FIFO MPSC queue to io_uring: multiple producers can insert items, while one consumer removes them. The post also points to the original design for an MPSC queue, from 2008.
The example shows how a lock-free queue design can be applied in the kernel. FIFO means items follow their order of entry; MPSC describes the relationship between multiple producers and a single consumer.
Because this is a proposed patch, do not mistake it for a feature already incorporated into the kernel. When studying the material, check the proposal’s status and code details before concluding how it behaves or whether it suits your use case.
