Wong" Source kernel commit: 6dfeb0c2ecde71d61af77f65eabbdd6ca9315161 When we're performing a bulk load of a btree, move the code that actually stores the btree record in the new btree block out of the generic code and into the individual ->get_record implementations. This is preparation for being able to store multiple records with a single indirect call. Signed-off-by: Darrick J.
