Detailed Description

ublk loop block device server using condy

This example demonstrates how condy's coroutine model simplifies writing a ublk server: the fetch -> perform I/O -> commit request/response loop becomes straight-line code, with one io_loop() coroutine per tag awaiting async_uring_cmd for fetch/commit and async_read/async_write/ async_fsync for the backing file.
