Subject: [PATCH] dm ebs: use dm_bufio_forget_buffers
Git-commit: 334b4fc17275667b38ebfd719714dab0edb83c6a
Patch-mainline: v5.8-rc1
References: bsc#1175995,jsc#SLE-15608
Use dm_bufio_forget_buffers instead of a block-by-block loop that
calls dm_bufio_forget. dm_bufio_forget_buffers is faster than the loop
because it searches for used buffers using rb-tree.
