The patch titled edac: core fix workq timer has been removed from the -mm tree. Its filename was edac-core-fix-workq-timer.patch This patch was dropped because it was merged into mainline or a subsystem tree The current -mm tree may be found at http://userweb.kernel.org/~akpm/mmotm/ ------------------------------------------------------ Subject: edac: core fix workq timer From: Arthur Jones <ajones@xxxxxxxxxxxx> When updating the edac_mc_poll_msec module parameter from the sysfs /sys/module/edac_core/parameters/edac_mc_poll_msec file, we don't update the workq timers. So that, if we move from a big poll time to a small one, the small one won't take effect until the big one has timed out. Here we provide a new module parameter set method to call out to the update routine. This brings the /sys/module/edac_core/parameters functionality up to that provided by the /sys/drivers/system/edac/mc sysfs module parameter files so that we can remove them or at least link to the /sys/module files...
