RE: [Xen-devel] [PATCH] [linux] xen: tmem: frontswap-tmemonly
> From: Konrad Rzeszutek Wilk
Can I add a "Reviewed-by:"? Or will this get
a S-O-B from you-as-maintainer anyway?
> This is a quite small file.. This is it?
Thanks for the review! Yes, this file is just a shim
translating kernel-ese to Xen-tmem-ese.
I realize I do need to add a tmem.h file (with one line
of code in it) to surface the exported tmem_enabled.

These must both be your editor (or maybe my mailer
if you are editing the inline version), they are fine
in the patch and in git.

I'm inclined to spell this out as it is. IMHO, at least in
this case, clarity trumps brevity. It is consistent with the
rest of the file too. If you feel strongly though, let me know.

Same here. I think a macro will obfuscate this code, and only will
remove a few lines. Again, if you feel strongly...

OK, will fix.
V2 to be posted soon.
Thanks,
