Subject: [PATCH 2/3] hrtimer: Remove public definition of HIGH_RES_NSEC
Date: Wed, 07 Jan 2026 11:36:57 +0100	[thread overview]
Message-ID: <20260107-hrtimer-header-cleanup-v1-2-1a698ef0ddae@linutronix.de> (raw)
In-Reply-To: <20260107-hrtimer-header-cleanup-v1-0-1a698ef0ddae@linutronix.de>

This constant is only used in a single place and is has a very generic
name polluting the global namespace.

Move the constant closer to its only user.
