  Thank you @joalif for troubleshooting the issue and finding the
  required commit.

  [impact]

  When hosting an NFS share that is sharing the home directory of users
  (e.g. /home), doing an "ls -l" on a client that has access to this
  share will return permission denied errors for each user before
  showing the output of the command. Below is an example output of the
  current version of ls:

  ghadi@nfs-client:/mnt/nfs_clientshare$ ls -l
  ls: test_user1: Permission denied
  ls: test_user2: Permission denied
  total 12
  drwxr-x--- 5 ghadi ghadi 4096 May  7 18:17 ghadi
  drwxr-x--- 2  1001  1001 4096 Jun 17 15:25 test_user1
  drwxr-x--- 2  1002  1002 4096 Jun 17 15:27 test_user2

  There has been a patch upstream to resolve this issue that I have
  already backported after some modifications to fit the current version
  of coreutils being used:
  https://cgit.git.savannah.gnu.org/cgit/coreutils.git/commit/?id=b58e321c8d5dd841f4170312692035a66b5ac149

  [Test Plan]

  1. On the NFS server create a few users and make sure they have a home directory:
   $ sudo useradd -m test_user1
   $ sudo useradd -m test_user2

  2. Then setup the NFS server and make sure to share /home

  3. On the client machine, mount the NFS share and run "ls -l"

  4. With the current version of coreutils you will see the following
  output:

  $ ghadi@nfs-client:/mnt/nfs_clientshare$ ls -l
  ls: test_user1: Permission denied
  ls: test_user2: Permission denied
  total 12
  drwxr-x--- 5 ghadi ghadi 4096 May  7 18:17 ghadi
  drwxr-x--- 2  1001  1001 4096 Jun 17 15:25 test_user1
  drwxr-x--- 2  1002  1002 4096 Jun 17 15:27 test_user2

  However in the patched version you will see the following:

  $ ghadi@nfs-client:/mnt/nfs_clientshare$ ls -l 
  total 12
  drwxr-x---  5 ghadi ghadi 4096 May  7 18:17 ghadi
  drwxr-x---? 2  1001  1001 4096 Jun 17 15:25 test_user1
  drwxr-x---? 2  1002  1002 4096 Jun 17 15:27 test_user2

  
    
  [Where problems could occur]

  * The patch adds "?" symbols when it cannot get the metadata which could cause issues with some scripts
  * Some errors that should be displayed might stop being displayed specially if they are related to reading file attributes (operations that involve the listxattr syscall)
