Is there a tree (git or hg ) which i can use to get a working online defrag ?
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 -aneesh - To unsubscribe from this list: send the line "unsubscribe linux-ext4" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
