The list of minor contributors is currently unsorted and contains people who have contributed code ``in some way'' (e.g. on the upstream or maintenance repositories), either through Git or email. Note that we have taken over the maintenance and further development of Herbert Haas' mausezahn [ˈmauzəˌtsa:n] utility after he passed away in 2011. There were no Git commit statistics available from the import of his project. The project is currently in a staging area, but will be fully integrated soon. (*) Want to join the core team? Submit enough great patches over a long time, implement what's on the TODO file and show an ongoing, active interest in supporting netsniff-ng. What's in it for you? If you ever come to Switzerland, you get a free beer on Daniel and you can meet some great people involved in this project. ;) class='cgit-panel'>diff options

x86/mce: Make timer handling more robust
Erik reported that on a preproduction hardware a CMCI storm triggers the BUG_ON in add_timer_on(). The reason is that the per CPU MCE timer is started by the CMCI logic before the MCE CPU hotplug callback starts the timer with add_timer_on(). So the timer is already queued which triggers the BUG. Using add_timer_on() is pretty pointless in this code because the timer is strictlty per CPU, initialized as pinned and all operations which arm the timer happen on the CPU to which the timer belongs. Simplify the whole machinery by using mod_timer() instead of add_timer_on() which avoids the problem because mod_timer() can handle already queued timers. Use __start_timer() everywhere so the earliest armed expiry time is preserved.
