Btrfs: map the inode item when doing fill_inode_item Instead of calling kmap_atomic for every thing we set in the inode item, map the entire inode item at the start and unmap it at the end. This makes a sequential dd of 400mb O_DIRECT something like 1% faster. Thanks, Signed-off-by: Josef Bacik <josef@redhat.com>
