It's still maintained in a sporadic sort of way --- I update it when
either I need it for something, or someone's downloaded it and asks
why it doesn't work agains kernel X.Y.Z.  I see a few downloads a
month.
So do you intend to pursue acceptance ? If so, do you think the netlink-based taskstats interface provided by the delay accounting patches could be an acceptable substitute for the interfaces you had (from an old lkml post, they appear to be /proc/tgid/msa and a syscall
based one) ?


My microstate accounting patch overlaps the delay accounting patch quite a
lot in functionality, (but I thnk mine is cleaner except for interrupt
time accounting... which the delay accounting patch doesn't do.  I
wanted to know how much time a thread *really* had on the processor,
subtracting off the time spent in interrupt handlers for some other
process).
Thanks. Will incorporate into a note on the mechanisms of the other accounting patches.
