This makes exposing bat_priv's atomic_ts storing boolean or uint values
a one-liner in the future. It also further reduces the amount of
duplicate code in bat_sysfs.c.

Additionally, the sysfs entries "aggregate_ogms" and "fragmentation"
get renamed to "aggregation" and "frag" for consistency reasons, they
match the *_enabled parts in bat_priv now.

Especially for this commit, I'm not quite sure, if the usage of
the macros is ok and appropritate or just a too extensive use / abuse
of them. So comments highly appreciated :).

Cheers, Linus

Just my personal preference. I suggest others comment as well.

I would probably break this up into 3 macros. 
(And problem rename to BOOL instead of SWITCH.)
BAT_ATTR_STORE_SWITCH()
BAT_ATTR_SHOW_SWITCH()
BAT_ATTR_SWITCH()

where BAT_ATTR_SWITCH() just invokes the other two.

Maybe turn the above into an inline function and then have the macro
define a tiny wrapper function which just calls the inline function?

This is small enough that it is O.K. as a macro.

Then the same again for BAT_ATTR_UINT...

Please change the last line (and the similar line) to "static BAT_ATTR(...."

And yes, I like the idea to remove some redundancy.

I don't quite understand why you want to rename these names. I like the 
"aggregate_ogms" as it makes clear what is being aggregated. 

Please keep in mind that the kernel people won't be happy if we modify the 
user space API. Right now, it is less of an issue but once we leave the 
staging tree it is mostly unchangeable.

Regards,
Marek
