Chandan Babu R b6785e279d xfs: Use struct xfs_bmdr_block instead of struct xfs_btree_block to calculate root node size ... The incore data fork of an inode stores the bmap btree root node as 'struct xfs_btree_block'. However, the ondisk version of the inode stores the bmap btree root node as a 'struct xfs_bmdr_block'. xfs_bmap_add_attrfork_btree() checks if the btree root node fits inside the data fork of the inode. However, it incorrectly uses 'struct xfs_btree_block' to compute the size of the bmap btree root node. Since size of 'struct xfs_btree_block' is larger than that of 'struct xfs_bmdr_block', xfs_bmap_add_attrfork_btree() could end up unnecessarily demoting the current root node as the child of newly allocated root node. This commit optimizes space usage by modifying xfs_bmap_add_attrfork_btree() to use 'struct xfs_bmdr_block' to check if the bmap btree root node fits inside the data fork of the inode.
