Issue #3251 has been updated by deef.

Due date set to 12/22/2020
Status changed from New to In Progress
% Done changed from 0 to 50

link() issue fixed for both hammer (commit c5adbbb2+ on master, d74465f2+ on 
RELEASE_5_8) and hammer2 (b6c0d52e+ master, 2d476770+ RELEASE_5_8).

However, I've been unable to reproduce chmod() issue... It works as expected 
for me on master. And according to the code, it should also work the same on 
RELEASE_5_8. Could anybody confirm, please? :)

----------------------------------------
Bug #3251: file ctime not updated as documented on chmod(), link()

----------------------------------------
The stat(2) man page claims:

     st_ctim       Time when file status was last changed (inode data
                   modification).  Changed by the chmod(2), chown(2), link(2),
                   mknod(2), rename(2), unlink(2), utimes(2) and write(2)
                   system calls.

but neither link() nor chmod() update ctim.tv_sec:

  $ pwd
  /home/tony/dev/perl/git/dflybugs
  $ cc -olink_ctime link_ctime.c
  $ ./link_ctime
  FAIL: chmod didn't update ctime
