Seyeong, could you please update the Test Case section of the SRU template
to reflect the usage of Ubuntu commands and not upstream/built commands?

Thanks,
Mauricio

  [Impact]

  rename.ul refuses to rename links that don't resolve.

  bionic rename.ul renames links whether or not they resolve (util-linux
  2.31.1-0.4ubuntu3.6).

  focal rename.ul refuses to rename links that don't resolve
  (regression) (util-linux 2.34-0.1ubuntu9).

  Eoan is EOL, so removed.

  
  [Test case]

  Commit has good test case. I paste it here

  Before:

    $ touch file-found
    $ ln -s file-found symlink-1
    $ ./rename sym symbolic- symlink-1	# XPASS.
    $ echo $?
    0

    $ ln -s file-not-found symlink-2
    $ ./rename sym symbolic- symlink-2	# FAIL! REGRESSION.
    rename: symlink-2: not accessible: No such file or directory
    $ echo $?
    1

    $ ./rename sym symbolic- symlink-3	# XFAIL.
    rename: symlink-3: not accessible: No such file or directory
    $ echo $?
    1

    $ touch file-found
    $ ./rename found existing file-found	# XPASS.
    $ echo $?
    0

    $ ./rename found existing file-not-found # XFAIL.
    rename: file-not-found: not accessible: No such file or directory
    $ echo $?
    1

  After:

    $ touch file-found
    $ ln -s file-found symlink-1
    $ ./rename sym symbolic- symlink-1	# XPASS.
    $ echo $?
    0

    $ ln -s file-not-found symlink-2
    $ ./rename sym symbolic- symlink-2	# PASS! REGRESSION FIXED.
    $ echo $?
    0

    $ ./rename sym symbolic- symlink-3	# XFAIL.
    rename: symlink-3: not accessible: No such file or directory
    $ echo $?
    1

    $ touch file-found
    $ ./rename found existing file-found	# XPASS.
    $ echo $?
    0

    $ ./rename found existing file-not-found # XFAIL.
    rename: file-not-found: not accessible: No such file or directory
    $ echo $?
    1

  
  [Regression Potential]
  This commit changes code that checking accessibility to file or sym link. 
  If this fails, rename command will not work properly.it could be crashed or causes failure of rename.
