mstone tells me that Copy-on-write support (which I would like to use in
upgrades) requires git commit c53121c04317d23aa60664e08933218ef66f3ed6
from the vserver git. (git://dev.laptop.org/users/mstone/olpc-2.6). From
IRC:
(02:40:52 PM) Ashsong_home: There are two fixes here, first the
generic_sendpage() infrastructure that makes CoW work and the changes to
olpc_defconfig that cause file permissions to be preserved across reboots
on JFFS2.
(02:41:24 PM) Ashsong_home: but if he adds me as a remote and runs git-
remote update, he should be able to just merge the stated commits and git
will do the right thing. (git remote add
git://dev.laptop.org/users/mstone/olpc-2.6)
(02:41:29 PM) Ashsong_home: We were trying to make this easy for him.
(02:42:37 PM) Ashsong_home: (Incidentally, I think he didn't commit those
changes because he wanted Dave to review the generic_sendpage stuff).
(02:43:18 PM) Ashsong_home: I'm told that Dave and Herbert talked and that
they agreed that since the sendpage patch was vserver-specific, Herbert
was the appropriate judge of its correctness and that Andres should
perform the merge.
(02:43:23 PM) Ashsong_home: However, that's just hearsay.
I need working COW to keep making progress on upgrades, which I'd like to
get into the builds early this week.
