Re: [PATCH 0/3] bulk-checkin: remove global transaction state

Justin Tobler [off-list ref] writes:

The bulk-checkin subsystem provides an interface to write objects to the
object database in a bulk transaction. The state of an ongoing
transaction is stored across several global variables. This series aims
to remove this global transaction state in favor of storing state in in
`struct object_database`. This is done in preparation for a follow-up
change where the goal is to eventually move these transaction interfaces
into "odb.h".

Wonderful.  I admit these global variables are left-over dropping of
my making.  Thanks for cleaning after me ;-)
