<pre style="margin-left: 2em; white-space: pre-wrap; white-space: -moz-pre-wrap; white-space: -pre-wrap; white-space: -o-pre-wrap; word-wrap: break-word;">This is not strictly related to your changes, but it looks a bit unusual to have one plain bool and two bool bitfields next to each other. Making all bools a bitfield won't make much difference now though because the compiler will always use more memory for this class in order to preserve the 4-byte or 8-byte alignment.
Another alignment-related issue is caused by your patch though: on a 64-bit system, moving the int member away from the bools will most likely increase sizeof(KCompletionPrivate) by 8 bytes because the compiler will add some padding to both in order to preserve the alignment of the neigbouring pointers.
It might not make a big difference because it's probably unusual to create thousands of KCompletionPrivate instances, but still, it seems unnecessary.
If one really wanted to make use of bitfields to save memory here, one could make 'order' a bitfield and move it next to the bools. </pre>
