CVE-2026-99067

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

btrfs: scrub: fix local root reference leak in scrub print warning inode()

When paths from inode() fails, scrub print warning inode() jumps to err without dropping the reference taken by btrfs get fs root(), leaking a reference to the root every time path resolution fails while printing scrub warnings. Every other error and success path of the function drops the reference.

Drop the reference on the paths from inode() failure path too.
