Tomas, > Commit 0c52310f2600 ("hrtimer: Ignore slack time for RT tasks in > schedule_hrtimeout_range()") effectivelly shortens a sleep in a > polling function in the driver. That is causing a performance > regression as the new value of just 2us is too low, in certain tests > the perf drop is ~30%. Fix this by adjusting the sleep to 20us (close > to the previous value). Applied to 6.12/scsi-staging, thanks! -- Martin K. Petersen Oracle Linux Engineering
