Btrfs-progs: fix some build warnings on 32bit platform
Fix following build warnings on 32bit platform: ... utils.c:1708:3: warning: left shift count >= width of type [enabled by default] if (x << i & (1UL << 63)) ^ qgroup-verify.c:393:9: warning: cast to pointer from integer of different size [-Wint-to-pointer-cast] return (struct tree_block *)unode->aux; ^ qgroup-verify.c:407:38: warning: cast from pointer to integer of different size [-Wpointer-to-int-cast] if (ulist_add(tree_blocks, bytenr, (unsigned long long)block, 0) >= 0) ^ cmds-restore.c:120:4: warning: format %lu expects argument of type long unsigned int, but argument 3 has type size_t [-Wformat=] fprintf(stderr, "bad compress length %lu\n", in_len); ... BTW, this patch also switches other castings with new helpers. Signed-off-by: Wang Shilong <> Signed-off-by: David Sterba <>
