Interesting that my gcc doesn't warn here. Strictly speaking, gcc isn't
wrong, but num_extent_pages() will always be at least 1. This function
is new in this pull, so it can't be a conflict.

Do you want a new pull with the ret = 0 patch?

int repair_eb_io_failure(struct btrfs_root *root, struct extent_buffer
int mirror_num)
struct btrfs_mapping_tree *map_tree = &root->fs_info->mapping_tree;
u64 start = eb->start;
unsigned long i, num_pages = num_extent_pages(eb->start, eb->len);
int ret;

for (i = 0; i < num_pages; i++) {
struct page *p = extent_buffer_page(eb, i);
ret = repair_io_failure(map_tree, start, PAGE_CACHE_SIZE,
start, p, mirror_num);
if (ret)

return ret;
