In commit 35a06697da ("FROMLIST: sched: Avoid placing RT threads on cores handling long softirqs"), the patch drop TASKLET_SOFTIRQ from LONG_SOFTIRQS.
Some drivers use tasklet softirq for data reception from firmware. When
there's a high volume or continuous stream of data from the firmware,
it can lead to unexpectedly long execution times for RT tasks and further cause jank or audio glitch.
Bug: 333895950
Test: check tasklet are defered when RT task is running
