Good finding.

Woundn't it be better to split this one into some logical parts,
tunning up part(decreasing delay) and cleanup part(the others)?
Home brewed MACROs themselves like UTIL_Wait() are basically evil from
kernel source readibility perspective, but keeping consistency within
specific module may be more important and this kind of cleaning up
would be better to be done at onece over a module, in separate
patches.
Hari,
Any comment? if it's ok, please merge it or newer ones into o-z as
well.
