About 10 years ago, there was a discussion about the poor performance of dummy_hcd due to the use of jiffies instead of hrtimers [1]. There was a proposal to switch to hrtimers, but the patch never made it into the mainline, and I cannot figure out why.
This patch set brings the idea back to the mailing list with the intention of improving the overall performance of this driver.
