[dm-devel] doubt about linear_ctr

["Sandeep Kumar" <sandeepksinha gmail com>]

Hi all,

#echo 0 100 linear /dev/hdd 0 | dmsetup create new
#dd if=/dev/zero count=1 of=/dev/mapper/new 



Well, I am trying to get the information printed from the bio structure, when the control comes to linear_ctr.
I found that the control comes to linear_ctr twice.

I have customized the linear_ctr  and have re-compiled the kernel.

Why is that so ?
Why two times ?
