Subject: btrfs: remove error message from search ioctl for nonexistent tree
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=11ea474f74709fc764fb7e80306e0776f94ce8b8;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

btrfs: remove error message from search ioctl for nonexistent tree

Let's remove the error message that appears when the tree_id is not
present. This can happen with the quota tree and has been observed in
practice. The applications are supposed to handle -ENOENT and we don't
need to report that in the system log as it's not a fatal error.
