This is what i tried.
GIT_DIR=/home/opensource/linux-2.6/.git git archive --format=tar
--prefix=linux-2.6.ext4/ v2.6.19-rc6 | tar -xv
That is 2.6.19-rc6.
now i downloaded the patches at
ftp://ftp.clusterfs.com/pub/people/alex/2.6.19-rc6/ and applied it in
the same order as found in the series. The patch doesn't apply
cleanly.
I have downloaded online patches at
http://article.gmane.org/gmane.comp.file-systems.ext4/1011-1014
