btrfs-progs: Fix btrfs fi show by uuid and label
Commit 8be2fff (btrfs-progs: apply realpath for btrfs fi show when mount point is given) changed the behavior of btrfs fi show to return an error if the call to realpath() failed. This broke the ability to specify a filesystem by uuid or label. So let's not consider a failed call to realpath() as an error. If the user really specified a bad device, just return nothing like we did before. Signed-off-by: Justin Maggard <> Reviewed-by: Gui Hecheng <> Signed-off-by: David Sterba <>
