SubjectPATCH: 2 small patches against 2.4.15-pre6 (sym2 + email change) (fwd)

Hi Marcelo,

I didn't see these patches applied by previous kernel maintainer, neither
received any ack nor nack about from. You may let me know if something
gets wrong with them. Btw, I have another one after those ones.

Note that I am used of the "no news means bad news" when patches for linux
development are in concern, but I guess that I am not the only guy who
will be glad if usual good practice of "no news means good news" would
also apply there. Let me hope that this will be changed as it has been
with 2.0 and 2.2 kernel maintainance. :)

By the way, I missed the postings that made you the maintainer of 2.4
kernel neither saw any comments from Alan about. I am sure that you will
do the best you can and will do a very good work, but I feel a bit
frustrated not to know the reasons of this decision. If you can point me
to the corresponding articles, I will be very interested in.

Thanks to people who tried, did or are doing Linux kernel maintainance as
I think that maintainance is a very important process at least as
important as development (I want to write a lot more, in fact...).

Good luck and TIA.
Gérard.

Subject: PATCH: 2 small patches against 2.4.15-pre6 (sym2 + email change)


Linus,

I have attached 2 small patches against linux-2.4.15-pre6 to this email.

roudier-email-for-2.4.15-pre6.patch:
This patch changes my email address in CREDITS, MAINTAINERS and
old sym53c8xx and ncr53c8xx drivers related files. It also bumps
Copyright up to year 2001 for these driver files.

sym-2.1.17-for-2.4.15-pre6.patch:
This patch is the result of the feed-back I got after the inclusion of
sym-2 into the main kernel stream. It fixes notably a couple of harmless
warnings. The only significant change applies to the allocation of
a 256 entries hash lists array that is now allocated separately from the
host data structure. This was needed on PPC64 / 4 KB page size, for the
driver not to try to allocate more than 1 PAGE at a time.

Thanks in advance for including these changes in next kernel release.

Regards,
Gérard.

Allowing disconnections is important if you use several devices on
your SCSI bus but often causes problems with buggy devices.
