[bug #17877] Invalid "No such file or directory" error on filesystem without stable inode numbers

[Geoff Clare]

Follow-up Comment #3, bug #17877 (project findutils):

POSIX does require a file's inode number to be stable.  To see this consider
what happens if you stat() a pathname and remember the st_dev and st_ino
values, then some time later you stat() the same pathname and observe that
the st_ino value is different.  POSIX says "The st_ino and st_dev fields
taken together uniquely identify the file within the system", therefore
st_ino being different means that the pathname now refers to a different
file.
