Hi members,
I am reading the Oreilly book and I am reading about the bio structure.
I am not able to understand its two fields:
|
unsigned short |
bi_phys_segments |
Number of physical segments of the bio after merging |
|
unsigned short |
bi_hw_segments |
Number of hardware segments after merging |
What is difference between physical segments and hardware segments?
Any help or link.
TIA.
