Hi Boris, please send me patches already formatted to be applied by patch
program, because the substitution of spaces with tabs and other indentation
characters requires a lot of time and it has never worked (or explain me how
to make it work :))
Anyhow, I have given a look to the patch compared to the original file. Is it
possible to apply to plain 2.6.27 kernel? From a brief look, it is very
different from 2.6.27 ide-cd.c file and maybe I need to download the
development branch of the kernel with GIT to apply it or a more recent
subversion like 2.6.27.2.
Waiting for you.
P.S: I have received messages from bugzilla, but I have subscribed to this
mailing list on Fujita's suggestion just to ease communication. What do you
prefer between bugzilla and linux-ide?
