So to try and speed things up I put my 'agk' hat on and tidied as I thought he would. The main things I did were remove the gratuitous gotos (eg, jumping from one branch of an if to another). I'm not sure moving dm-bufio to pdata was the right thing to do. My rationale was there's only one user atm, so put it in there. I don't think the header should be in include/linux, this is not going to be used outside dm (dm-io.h should be either). This isn't set in stone, take this up with agk. - Joe -- dm-devel mailing list dm-devel@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/dm-devel
