No problem, AFAIK these aren't queued anywhere and after having done a
wider sweep, there are some 300+ of them (that give a net removal of ~5k
lines of dead code) with some in maintainer-less code; so it looks like
I'll inevitably have residuals that I'll have to ask Linus to pull directly.

Anyway, thanks for trying to modularize it. I'll add the reviewed tags
and update the commit log on the other one to add your comment.

Simple.  I'm making the code consistent with its current behaviour.
I'm not looking to extend functionality in code that I don't know
intimately.  I can't do that and do it reliably and guarantee it
works as a module when it has never been used as such before.

I've got about 130 of these and counting.  Some of them have been bool
since before git history ; before the turn of the century.  If there was
demand for them to be tristate, then it would have happened by now.  So
clearly there is no point in looking at making _those_ tristate.

I did have one uart driver author indicate that he _meant_ his code to
be tristate, and he tested it as such, and asked if I would convert it
to tristate on his behalf.  And that was fine and I did exactly that.

But unless there are interested users who want their code tristate and
can vouch that their code works OK as such, I can only make the code
consistent with the implicit non-modular behaviour that the Kconfig and
Makefiles have dictated up to now.  Are there such users for CLEANCACHE?

[PATCH 01/10] mm: make cleancache.c explicitly non-modular

2015-08-24 Thread Paul Gortmaker
The Kconfig currently controlling compilation of this code is:

config CLEANCACHE
bool "Enable cleancache driver to cache clean pages if tmem is present"

...meaning that it currently is not being built as a module by anyone.

Lets remove the couple traces of modularity so that when reading the
driver there is no doubt it is builtin-only.

Since module_init translates to device_initcall in the non-modular
case, the init ordering remains unchanged with this commit.

Why not make it a tristate?



Lets remove the couple traces of modularity so that when reading the
driver there is no doubt it is builtin-only.

Since module_init translates to device_initcall in the non-modular
case, the init ordering remains unchanged with this commit.

 Why not make it a tristate?

Simple.  I'm making the code consistent with its current behaviour.
I'm not looking to extend functionality in code that I don't know
intimately.  I can't do that and do it reliably and guarantee it
works as a module when it has never been used as such before.

I've got about 130 of these and counting.  Some of them have been bool
since before git history ; before the turn of the century.  If there was
demand for them to be tristate, then it would have happened by now.  So
clearly there is no point in looking at making _those_ tristate.

I did have one uart driver author indicate that he _meant_ his code to
be tristate, and he tested it as such, and asked if I would convert it
to tristate on his behalf.  And that was fine and I did exactly that.

But unless there are interested users who want their code tristate and
can vouch that their code works OK as such, I can only make the code
consistent with the implicit non-modular behaviour that the Kconfig and
Makefiles have dictated up to now.  Are there such users for CLEANCACHE?

Paul.
