Linux patch proposes lock-free MPSC queue for io_uring
Published on June 11, 2026, the Linux kernel patch proposes adding a lockless FIFO queue with multiple producers and one consumer to io_uring.
A Linux kernel patch proposes adding a lock-free FIFO queue to io_uring, with multiple producers and one consumer (MPSC). The publication also points to the original design for an MPSC queue from 2008 and presents the patch as a concrete example of a lock-free queue applied in the kernel.
The proposal should not be mistaken for a change already merged into the kernel: the text identifies it as a patch. To verify its details and status, consult the original publication and compare the patch with the 2008 design it references.
