Description

Accessing the filesystem root by its FID fails with EINVAL. It seems that master and 2.3 are affected.

$ lfs path2fid /mnt/lustre
[0x200000007:0x1:0x0]
$ ls /mnt/lustre
$ ls /mnt/lustre/.lustre/fid/0x200000007:0x1:0x0
ls: cannot access /mnt/lustre/.lustre/fid/0x200000007:0x1:0x0: Invalid argument
