H A Dfuse-io-uring.rst7 This documentation covers basic details how the fuse

17 is required to also handle requests through /dev/fuse after io-uring setup
24 Fuse kernel requests are queued through the classical /dev/fuse
27 In order to set up fuse-over-io-uring fuse-server (user-space)
28 needs to submit SQEs (opcode = IORING_OP_URING_CMD) to the /dev/fuse
35 Note, every CPU core has its own fuse-io-uring queue.
36 Userspace handles the CQE/fuse-request and submits the result as
