I previously sent a copy of my interrupt.h to the list, may have been rejected because I attached the file rather than copied inline. I downloaded the patches file for 4.11.12-rt14 and searching for tasklet_hrtimer_init() I find this reference: 0022-softirq-Remove-tasklet_hrtimer.patch:-tasklet_hrtimer_init(struct tasklet_hrtimer *ttimer, The very top lines of that 0022 patch file are these: --------- From: Thomas Gleixner <tglx@xxxxxxxxxxxxx> Date: Thu, 31 Aug 2017 11:03:11 +0000 Subject: [PATCH 22/25] softirq: Remove tasklet_hrtimer There are no more tasklet_hrtimer users of this interface.
