[Xen-devel] find_next{,_zero}_bit() inconsistencies

["Jan Beulich" <JBeulich@xxxxxxxx>]

Hello,

in the context of
https://lists.xenproject.org/archives/html/xen-devel/2016-08/msg03068.html
I once again came across the different behavior our various
implementations of the $subject functions, in particular their varying
handling of the offset argument being greater / greater-or-equal
the size argument. Shouldn't we settle on a single, uniform model,
which might be
1) offset >= size is valid, returns size,
2) offset == size is valid, returns size, offset > size is invalid,
3) offset >= size is invalid.

Thanks for opinions, Jan
