#1248134 — [PATCH 2/9] KVM: arm: Do not indent the arguments of DECLARE_BITMAP

Besides being a coding style issue, it confuses make tags:

ctags: Warning: include/kvm/arm_vgic.h:307: null expansion of name pattern "\1"
ctags: Warning: include/kvm/arm_vgic.h:308: null expansion of name pattern "\1"
ctags: Warning: include/kvm/arm_vgic.h:309: null expansion of name pattern "\1"
ctags: Warning: include/kvm/arm_vgic.h:317: null expansion of name pattern "\1"

Is not being able to deal with a whitespace not a make tags problem?

As for coding style, do we really entertain these kinds of changes just
to adhere to a coding style?  It feels unnecessary taints the log etc.

However, I'm curious what the general concesus and previous practice for
this sort of thing is?

Thanks,

Yes, but the regular expressions are hardly readable already :-(.

I wouldn't have submitted this just for the sake of coding style, it was
the ctags warning prompted me to do so.

This KVM header was the only instance where whitespace confused the
patterns, so I'd say it's established practice not to do this. The other
ctags warnings were about multi-line macro invocations, where the
line-oriented regular expression rules cannot work.
