I am getting a request with bvec->bv_len > 512. Now, the<br>
information to be read is scattered across the entire disk in 512<br>
chunks. So that, information on disk can be : sector 8, sector 100,<br>
sector 9.<br>
Now if i get a request to read with the bvec->bv_len > 512 i need to<br>
pull in the information from<br>
multiple places on disk since the data is not sequentially located.<br>
I tried to look at the linux source code because i think raid must be<br>
doing it all the time. (eg : on disk 1 we may be storing sector 6 and<br>
on disk 2 we may be storing sector 7 and so on).<br>
However, i have not really got any useful information from it. Also<br>
scouring through articles on<br>
google has not helped much.<br>
I am hoping somebody points me in the right direction.<br>
<br>
Thanks in advance,<br>
