We encountered a file not found error when the symlink filesize is
equal to 60:
$ ls -l initrd
lrwxrwxrwx 1 root root 60 Jan 6 16:37 initrd -> secure-core-image-initramfs-5.10.2-yoctodev-standard.cpio.gz
When booting, we got the following error in the GRUB:
error: file `/initrd' not found
The root cause is that the size of diro->inode.symlink is equal to 60
and a symlink name has to be terminated with NUL there. So, if the
symlink filesize is exactly 60 then it is also stored in a separate
block rather than in the inode itself.
