Summary
btrfs: fix uninitialized pointer free in add_inode_ref()
Details

In the Linux kernel, the following vulnerability has been resolved:

btrfs: fix uninitialized pointer free in addinoderef()

The addinoderef() function does not initialize the "name" struct when it is declared. If any of the following calls to "readoneinode() returns NULL,

dir = read_one_inode(root, parent_objectid);
if (!dir) {
    ret = -ENOENT;
    goto out;
}

inode = read_one_inode(root, inode_objectid);
if (!inode) {
    ret = -EIO;
    goto out;
}

then "name.name" would be freed on "out" before being initialized.

out: ... kfree(name.name);

This issue was reported by Coverity with CID 1526744.
