ext4: remove an unused statement in ext4_mb_get_buddy_page_lock()
In this patch, the statement "poff = block % blocks_per_page" in ext4_mb_get_buddy_page_lock has no effect. It will be optimized out by the compiler, but it's better to remove it. Signed-off-by: Haibo Liu <HaiboLiu6@gmail.com> Signed-off-by: "Theodore Ts'o" <tytso@mit.edu>
