Hello,
How can I manually create a installable reiser4 rpm module for a new
kernel, because the opensuse build service seems stuck on a older kernel .
I need all of the steps please, (commands please) so I can create the
installable rpm module.
Hi Glenn -
Hello everyone.
I'm afraid it's not as simple as a series of commands. I do need to
update the patch to the 2.6.29 version
ah, you maintain 2.6.small_nr + series of patches..?
which doesn't have the
- ->commit_write and ->prepare_write hooks that have been removed.
this goes here:
http://userweb.kernel.org/~akpm/mmotm/broken-out/reiser4-adjust-to-the-new-aops.patch
The
other thing is that it needs more support in the kernel itself.
Previously it was limited to exports and adding a new hook, which I
could accept without much worry. I'm concerned about whether
set_buffers_dirty_notag() will make it upstream and I'm uncertain of the
interactions.
I think it'll be pushed to upstream simultaneously with reiser4,
unless someone needs to not tag every dirty page in the radix tree..
Edward - What's the reasoning behind it?
The reason is to reduce a cost of maintenance.
Since reiser4_set_page_internal() is not in vfs library
bad things are bound to happen. For example, set_page_dirty()
and friends were modified by vfs folks to update dirty pages
accounting and of course nobody knew that there are other
"friends" in reiser4 code, so I have spent a lot of time to figure
out why oom kills processes of dbench 190...
Has it been submitted upstream
yet?
Nup, this is in -mm
Is it possible to use reiser4_set_dirty_pages creatively to get
the same effect?
Sure.
Just modify it to update dirty page accounting
(2 strings or so need to be added).
Note, that there were 2 friends in reiser4 to modify:
reiser4_set_page_dirty() and reiser4_set_page_dirty_internal().
Edward.

2. In the past, I've used the reiser4-kmp-default-0.1_2.6.27.7_9.1-27.3
(2.6.27.7-9-default) opensuse 11.1 with good success and has worked well
for me.

How can I manually create a installable reiser4 rpm module.
I need all of the steps please, (commands please) so I can create the rpm
module with the three files (see below).
Other references I looked at but I did not understand the reiser4.spec and
how the files (see below) are generated and packaged for a newer kernel..
# rpm -qlp reiser4-kmp-default-0.1_2.6.27.7_9.1-27.3.x86_64.rpm

Thankyou for your help and time.
