I agree about kernel version, but why DM version of 1.02.77 is also old? 
I though that I am using the latest version of DM referenced by these 
sources:

"Releases
The userspace code (dmsetup and libdevmapper) is now maintained 
alongside the LVM2 source available from http://sources.redhat.com/lvm2/."

http://www.sourceware.org/dm/

and

"Source code

The source code is stored in git and can be accessed with git clone 
git://git.fedorahosted.org/git/lvm2.git
There is a web interface to git at http://git.fedorahosted.org/git/lvm2.git"

http://sources.redhat.com/lvm2/

so finally I've got DM of version 1.02.77 within lvm2 package of version 
2.02.98 from http://git.fedorahosted.org/git/lvm2.git, it's of latest 
released version in the provided list.
Most recent lvm2 package from master branch of 2.02.99 version contains 
DM ofversion 1.02.78 which has no attribute "drop_writes" in sources as 
well.

Thanks,
