From: Thomas Gleixner Date: Tue, 24 Feb 2026 16:36:15 +0000 (+0100) Subject: clockevents: Remove redundant CLOCK_EVT_FEAT_KTIME X-Git-Url: http://git.ipfire.org/gitweb.cgi?a=commitdiff_plain;h=70802807398c65f5a49b2baec87e1f6c8db43de6;p=thirdparty%2Fkernel%2Flinux.git clockevents: Remove redundant CLOCK_EVT_FEAT_KTIME The only real usecase for this is the hrtimer based broadcast device. No point in using two different feature flags for this.
