HI~~
I look over source of “fastfat.sys” in IFS KIT.
I can see “IoRuns” array so many times
but I can’t know it.
What is IoRuns?

It’s a data structure that describes write requests that are to take
part in parallel, asynchronously. You can find the definition in one of
the include files, and a small description.

Since the use of the IoRuns array is completely internal to FAT, you
really should consider reading the source code closely enough to figure
out how it is used. This approach will pay off if you plan to use the
FAT code as reference. If you have any specific questions after doing
so, by all means ask out here and I’m sure someone will pick it up.

The IoRuns arrays really aren’t anything special, just a grungy old
implementation detail.
