Subject: [PATCH 10/13] gfs: Use fixed GL_GLOCK_MIN_HOLD time
Date: Fri, 23 Jan 2026 16:31:00 +0100 [thread overview]
Message-ID: <20260123153105.797382-11-agruenba@redhat.com> (raw)
In-Reply-To: <20260123153105.797382-1-agruenba@redhat.com>
GL_GLOCK_MIN_HOLD represents the minimum time (in jiffies) that a glock
should be held before being eligible for release. It is currently
defined as 10, meaning that the duration depends on the timer interrupt
frequency (CONFIG_HZ). Change that time to a constant 10ms independent
of CONFIG_HZ. On CONFIG_HZ=1000 systems, the value remains the same.
