• cb152ff26   sched: Fix /proc/sched_stat failure on very very large systems ... Browse Code »

  On systems with 4096 cores doing a cat /proc/sched_stat fails,
  because we are trying to push all the data into a single kmalloc
  buffer.

  The issue is on these very large machines all the data will not
  fit in 4mb.

  A better solution is to not use the single_open() mechanism but
  to provide our own seq_operations.

  The output should be identical to previous version and thus not
  need the version number.

• 30fd049af   sched: Remove sched_switch ... Browse Code »

  Currently we don't utilize the sched_switch field anymore.

  But, simply removing sched_switch field from the middle of the
  sched_stat output will break tools.

  So, to stay compatible we hardcode it to zero and remove the
  field from the scheduler data structures.

  Update the schedstat documentation accordingly.

  There's too many sched*.[ch] files in kernel/, give them their own
  directory.

  (No code changed, other than Makefile glue added.)
