Subject: [PATCH 0/3] unwind_user: Cleanups
Date: Tue, 25 Nov 2025 17:43:46 +0100	[thread overview]
Message-ID: <20251125164349.2592874-1-jremus@linux.ibm.com> (raw)

This patch series applies on top of Peter Zijlstras' latest unwind user
enhancements (and perf deferred callchain support) on his tip perf/core
branch:

  git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip.git perf/core

Which has already been merged to tip/master and linux-next/master.

Patch 1 enhances a few comments in unwind_user_next_common().

Patch 2 gets rid of an ifdef in unwind_user_next_fp() by moving it to
linux/unwind_user.h.

Patch 3 ensures the x86 unwind_user_word_size() implementation is
available whenever config option UNWIND_USER is enabled, as it is
required by unwind user in general and is not specific to its FP
unwind method.

Regards,
Jens
