Subject: [patch 00/15] clocksource/events: Overhaul (un)registration
Date: Thu, 25 Apr 2013 20:31:42 -0000 [thread overview]
Message-ID: <20130425142452.908423538@linutronix.de> (raw)
The clocksource_unregister() interface is broken. A clocksource can be
removed unconditionally even if there is no fallback clocksource
available. clocksources in a module can be removed as well. Aside of
that the registration part lacks a few sanity checks as well.
The clockevents layer does not allow unregistration, but for
reconfigurable hardware this is a must have feature.
The following patch series fixes the clocksource part and adds
unregister support for clockevent devices.
Thanks,
tglx
