Hi, all...
I have read plenty books about VFS. Comparing designs from Linux and UNIX-likes.
Linux's bread() will end up in disk driver's request() handler. But a book said that in some UNIX-like kernels, it will calls bread() from vnode/inode (struct inode_operations) who represented for specific disk devices.

Actually, I like simpler second method. But in doubt, I want to clarify what I was said from the book.
Is it right that some UNIX-likes using bread() inode/vnode operation? If so, why there are strategy() operation inside it too?

Thanks before..

Code: Select all

loaf * bread()
{
     return malloc( sizeof( loaf ) );
}

Sorry, couldn't resist.

First, take 4 cups of whole wheat flour, a cup and a half of milk, and two eggs...

OK, how about block_read()?. It was not so delicious as bread() taste like..

I can't help it either. You need wheat, a few other ingredients and yeast

search C manuals... that might help
