Hi,
 
For=20 understanding the LVM and Snapshot module, I am going through = the
source code=20 for solving some of my queries like
 -How does it allocate space = for=20 creating snapshot?
 -Does it create snapshot on the same=20 volume?
 -How does it copy the buffer to snapshot?
 
= To move=20 in further details I have compiled the LVM source code for=20 debugging.
But after giving some of the printk statements in the = code=20 for understanding the flow the print statement of lvm.c get printed but=20 the
print statement in lvm-snap.c is not getting = printed.
 
Can=20 any one give some pointer to solve this or any other better approach=20 to
 solve my above queries?
 
> Thanks in=20 advance
Mekhala
