Cleanup Patches

Cleanup Patches

[Alex Elder]

I'm about to post several series that contain a bunch of
cleanups.  The motivation for this is to simplify some code
before setting out to refactor it, to eliminate any unneeded
complexity.

I've grouped them into smaller series though the patches in
a series may not appear to be logically connected.

These have all been tested together though, and were
applied in the sequence shown below.  They're available
in the branch "wip-osd-cleanup" on the ceph-client git
repository.

These are results from bisecting of R4 slowdown with ccreg40 plugin
with config and scripts I used, first double run is to see dispersion
of consecutive tests:

Reiser4 patch        Real        User        System

And some new relevant ones:

2.6.29            2m57.027s    0m3.096s    1m33.266s
3.17.2            2m34.                            1m20.

3.17 is cropped because I copied it by hand as network didn't work
with old userspace.

Is this issue closed now?

Thank you for your work!
TBH, I thought that the performance issue introduced in 2.6.21-rc3
still takes place in modern kernels..

Cleanup patches.

[Martin Schwidefsky]

Hi Andrew,
got no feedback for my cputime patches so far. I guess this is fate.
The first three of the patches are cleanup which do not add anything
new. I think they are worthwhile to add, probably something for -mm?
So I sent them to you and linux-arch for consideration. Have fun.

blue skies,
  Martin.
