[PATCH] SCSI trees, merges and git status
Doing the latest SCSI merge exposed two bugs in your merge script:
1) It doesn't like a completely new directory (the misc tree contains a
new drivers/scsi/lpfc)
2) the merge testing logic is wrong. You only want to exit 1 if the
merge fails.

[PATCH] provide better committer information to commit-tree.c
Here's a small patch to commit-tree.c that does two things:
- allows the committer email address and name to be overridden
by environment variables (if you don't like the environment
variable names I've used (COMMIT_AUTHOR_NAME,
COMMIT_AUTHOR_EMAIL), feel free to change them.)
- provide the proper domainname to the author/committer email
address (otherwise, my address was only showing up as from the
hostname.)
This allows people to set sane values for the commit names and email
addresses, preventing odd, private hostnames and domains from being
exposed to the world.

Add the simple scripts I used to do a merge with content conflicts.
They sure as hell aren't perfect, but they allow you to do:
./git-pull-script {other-git-directory}
to do the initial merge, and if that had content clashes, you do
merge-cache ./git-merge-one-file-script -a
which tries to auto-merge. When/if the auto-merge fails, it will
leave the last file in your working directory, and you can edit
it and then when you're happy you can do "update-cache filename"
on it. Re-do the merge-cache thing until there are no files left
to be merged, and now you can write the tree and commit:
write-tree
commit-tree .... -p $(cat .git/HEAD) -p $(cat .git/MERGE_HEAD)

[PATCH] fix bug in read-cache.c which loses files when merging a tree
I noticed this when I tried a non-trivial scsi merge and checked the
results against BK. The problem is that remove_entry_at() actually
decrements active_nr, so decrementing it in add_cache_entry() before
calling remove_entry_at() is a double decrement (hence we lose cache
entries at the end).
