xfs: use deferred frees to reap old btree blocksrepair-reap-fixes_2021-12-15
Use deferred frees (EFIs) to reap the blocks of a btree that we just replaced. This helps us to shrink the window in which those old blocks could be lost due to a system crash, though we try to flush the EFIs every few hundred blocks so that we don't also overflow the transaction reservations during and after we commit the new btree.
