Subject: [PATCH v2 0/1] hrtimer: More fixes for handling of timer slack of rt tasks
This series fixes the (hopefully) last location of an incorrectly
handled timer slack on rt tasks in hrtimer_start_range_ns(), which was
uncovered by a userland change in glibc 2.33.
Changes since v1:
- drop patch "hrtimer: Document, that PI boosted tasks have no timer slack", as
this behavior is incorrect and is already adressed in 20240610192018.1567075-1-qyousef@...alina.io
- use task_is_realtime() instead of rt_task()
- fix style of commit message
v1 discussion: https://lore.kernel.org/lkml/20240805124116.21394-1-felix.moessbauer@siemens.com
Best regards,
