Btrfs: don't pre-allocate btrfs bio We pre-allocate a btrfs bio with fixed size, and then may re-allocate memory if we find stripes are bigger than the fixed size. But this pre-allocation is not necessary. Also we don't have to calcuate the stripe number twice. Signed-off-by: Li Zefan <lizf@cn.fujitsu.com>
