+Subject: [PATCH] btrfs-progs: subvolume: fix a bug that leads to unnecessary
+ error message
+
+[BUG]
+When a btrfs is mounted with "user_subvol_rm_allowed" mount option,
+unprivileged users are allowed to delete a subvolume using "btrfs
+subvolume delete" command.
+
+But in that case, there is always a warning message:
+
+ $ btrfs subvolume delete /mnt/btrfs/dir1/subv1/
+ WARNING: cannot read default subvolume id: Operation not permitted
+ Delete subvolume 257 (no-commit): '/mnt/btrfs/dir1/subv1'
+
+[CAUSE]
+The warning message is caused by tree search ioctl, which is to
+determine if we're deleting the default subvolume.
+This search is just to give a more helpful error message, and even
+without it deleting the default subvolume will fail anyway.
+
+Thus commit 0e66228959c4 ("btrfs-progs: subvol delete: hide a warning on
+an unprivileged delete") tries to hide the warning for unprivileged
+users.
+
+But unfortunately the function geteuid() returns the effective user id,
+thus we should hide the warning for non-zero uid, not the opposite.
+
+[FIX]
+Change the condition to output the warning only when the uid is 0.
