I don't know of a git / cvs repo. But you can pull down a tarball for any of
the releases.
See http://sourceforge.net/projects/hdparm/files/
Just view "all files" and click on the little pointer beside hdparm at:
=== As to patching vs. a new release:
I strongly suspect many SSDs don't work with the TRIM feature of hdparm 9.22
and 9.28 releases, but due to very limited testing, we don't have bugzillas to
show it.

I haven't read thru the release notes / changes for each release, but I think
you'll find that the only part of hdparm that has been getting updates in the
last couple years is the SSD TRIM handling feature which was new a couple years
ago or less.
So if you feel it is warranted, you can compare the source and only patch in
the code changes relevant to TRIM, but my guess is that will be all the
changes. Thus if I were doing it, I'd just do a full update.
fyi: The TRIM portion of the ATA8 draft spec has been seeing changes and also
many non-compliant SSDs have been released of the last couple years.
As such hdparm has been trying to keep up with both spec changes and real-world
reality. The biggest change I know of from 9.28 to 9.30 is reducing the
default TRIM payload from 1 MB to 512 bytes (I think). That was done because
all known SSDs handle at least one sectors worth trim payload, but several
apparently don't support more than that.
That one patch may make many SSDs that currently don't work with hdparm work.
(ie. Intel SSDs were believed not to work prior to that change, but I haven't
seen any official bugzillas, but neither have I seen any success reports.)
I doubt 9.22 even tries to read the max payload size attribute from a compliant
SSD. I first heard about that attribute just a few months ago, but Mark Lord
said at the time that hdparm already had support for it built-in.
