That's a _huge_ stack you are talking about here involving a vfs, the
memory management core, a filesystem, block layer, SCSI, and USB, at the
very least.

What _exactly_ are you looking to understand here?  And where in the
code have you looked and need help with?  What documents have you read
that were unclear?  And why do you need this information?
