more information about my class and my test.
I add some log on the read function of my class.
and notice that if i do some read on disk1s1, my read function will be called.
if i do some read on disks1, my read function will not be called.
my read operations like this:(using terminal)
#dd if=/dev/disk1s1 of=/dev/null bs=4096 count=256
this will result my read function be called.
If i do
#dd if=/dev/disk1 of=/dev/null bs=4096 count=256
my read will not be called.
