![]() When running with 4096 cores attemping to read /proc/timer_list will fail with an ENOMEM condition. On a sufficantly large systems the total amount of data is more then 4mb, so it won't fit into a single buffer. The failure can also occur on smaller systems when memory fragmentation is high as reported by Dave Jones. Convert /proc/timer_list to a proper seq_file with its own iterator. This is a little more complex given that we have to make two passes with two separate headers. sysrq_timer_list_show also needed to be updated to reflect the fact that now timer_list_show only does one cpu at at time.
