link() messes up file attributes

["ZINKEVICIUS,MATT (HP-Loveland,ex1)" <matt_zinkevicius@xxxxxx>]

Hi gang,

We have been running specSFSv2 (NFS benchmark) against a server running XFS.
All was well previously (kernel 2.4.14), but we recently checked out the XFS
CVS (2002-01-03) and it now fails. The test fails a part of the validation
stage which does the following steps:

1) Create a file (file1) with permissions 666
2) Create a hardlinked file (file2) to file1
3) Check that permissions of file1 are still 666 

Step 3 now fails as file1 now has 644 permissions! Using the same kernel we
tried ext2 instead and everything behaved normally. If anybody wants anymore
detail just let me know.
