GitHub PR hooks that block any change to the file which doesn't include a
documentation patch including those strings?
I don't think anything weaker is likely to be reliable. :)

Re: [ceph-users] A Jewel in the rough? (cache tier bugs and documentation omissions)

[Ken Dreyer]

At a general level, is there any way we could update the documentation
automatically whenever src/common/config_opts.h changes?

Mark fixed it in this commit, but looks like it was never marked for backport 
to Jewel.

https://github.com/ceph/ceph/commit/793ceac2f3d5a2c404ac50569c44a21de6001b62

I will look into getting the documentation updated for these settings.

No there isn't AFAIK, you'd think that an issue that has (had) both Mark's
and Sage's attention doesn't require some external lowlife to prod things
ahead.

A PR suggests somebody (i.e. me) having a solution or fixed documentation
handy, which w/o any intimate knowledge of the code may be worse than the
current state of affairs.

Alas bug reports/tracker items clearly don't work/help:

[ceph-users] A Jewel in the rough? (cache tier bugs and documentation omissions)

[Christian Balzer]

Hello,

It's now 10 months after this thread:

http://www.spinics.net/lists/ceph-users/msg27497.html (plus next message)

and we're at the fifth iteration of Jewel and still

osd_tier_promote_max_objects_sec
and
osd_tier_promote_max_bytes_sec

are neither documented (master or jewel), nor mentioned in the changelogs
and most importantly STILL default to the broken reverse settings above.

Anybody coming from Hammer or even starting with Jewel and using cache
tiering will be having a VERY bad experience. 

Christian
