Subject: Btrfs: fix check_path_shared so it returns the right value
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=dedefd7215d3ec451291ca393e5c8e4c1882c8c6;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git

Btrfs: fix check_path_shared so it returns the right value

When running xfstests 224 I kept getting ENOSPC when trying to remove the files,
and this is because we were returning ret from check_path_shared while it was
uninitalized, which isn't right.  Fix this to return 0 properly, and now
xfstests 224 doesn't freak out when it tries to clean itself up.  Thanks,
