Bear in mind that there will be 20 or 30 different trees which I'll need the diffs for, not just the one git-net. I don't know if it'll be successful continually merging all those trees together. The way I did this with bk was to have a separate repo for each tree, but I don't think I'll want 30-40 separate git trees. My little methodology worked nicely for git-ia64. Jan Harkes has pointed out that the problem here is that Linus and Dave both applied the same patch from Al and that interdiff was able to fix it up: $ git diff -r 25ee7e3832951cf5896b194f6cd929a44863f419:b453257f057b834fdf9f4a6ad6133598b79bd982 > git-linus.patch $ git diff -r 25ee7e3832951cf5896b194f6cd929a44863f419:5523662c4cd585b892811d7bb3e25d9a787e19b3 > git-net.patch $ interdiff --no-revert-omitted -p1 git-linus.patch git-net.patch | diffstat drivers/net/tg3.c | 73 ++++++++++++++------------- net/ipv4/ip_output.c | 2 net/ipv4/netfilter/ip_conntrack_ftp.c | 4 - net/ipv4/netfilter/ip_conntrack_standalone.c | 7 -- net/ipv4/tcp_input.c | 1 net/sched/simple.c | 18 ------ 6 files changed, 46 insertions(+), 59 deletions(-) So hm. I guess git did what it was supposed to do here, and that a `git merge' would have removed the common patch. But if I take the approach of merging all those subsystem trees I do wonder if things will come unstuck... - To unsubscribe from this list: send the line "unsubscribe git" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.htmlReceived on Wed Apr 27 04:56:59 2005
