Thanks for taking the effort for looking this up.
However, the function in question - newstat_copyout - is not in 'action'
here. (had set a breakpoint in ddb)
It's still unclear to me what recent change broke vmware.
The removal of block devices Julian referred to is not something recent,
is it?
I mentioned earlier to you that I am writing a linux_read system call.
This will basicly work, as long as I will be able to do the following (in
pseudo code):
linux_read(readsize) {
if (read_is_on_raw_device)
readlen = (readlen % BLOCKSIZE) + BLOCKSIZE;
/* or something like this plus some other mangling of the buffer
*/
read(readlen);
}
The only thing I have to find out is the check to see whether it is a read
on a raw device or not. I strongly prefer to do the check in linux_read
and not in the disk layer code. (It would be easier, but not cleaner)
