Kernel Newbiews maintains a useful summary of all the changes going into
the latest version of the Linux kernel. Oh well, that I've come to
expect; at least you get a copyright notice in the bootup and somewhere
in the comments give me credit for proving it's possible.
So i'd move syslets into the same category as raw syscalls: pieces of
the raw infrastructure between the kernel and glibc, not an exposed API
to apps. (even if there are multiple processes active and their syslets
intermix) throttling of outstanding async contexts is most easily done
by user-space - you can see an example in threadlet-test. 6 kernel how
to change color of taskbar w.
I found generic rbtree code to generally be slower, certainly because of
the call to a function with arguments on every node. The only
association with futex I have is RedHat Linux 8' s RPM: it was hanging
all the time you try to run it.
A separate scheduling policy requires a userspace change to even
benefit from it. That result was just a side-effect of it.
a fairness based cpu scheduler policy.
The downside is that I never found how to make this algo fit in
O(log(n)). This would be a really, really good thing for Linux and its
users. In some areas (you know who you are) it may even be true.
Reads are where it matters.
If you're interested, I can try to see how that would fit (but not this
week-end). the new scheding classes code in the CFS patch was not a
result of "oh, i want to write a new scheduler, lets make schedulers
pluggable" kind of thinking. Oh well, that I've come to expect; at
least you get a copyright notice in the bootup and somewhere in the
comments give me credit for proving it's possible. Syslets (small,
kernel-side, scripted "syscall plugins") are still supported - they are

K. What would we win from another fancy toy? c is less of a problem.
I got rid of the explicit cache-hot tracking code and replaced it with a
more natural pure 'pick the next-to-run task first, that is likely the
most cache-cold one' logic. This is, I don't know what exactly to call
it, but an interesting way of making it look like there is now more
choice. 21-rc1 compared to 2. c (see the async-test-v3. ) The code must
be thread-safe, because the kernel can move execution to a new thread
anytime and then it will execute in parallel with the main thread. I
guess I have lots to put into -ck still.
