Description Nithya Balachandran 2018-08-29 03:33:01 UTC

+++ This bug was initially created as a clone of Bug #1619720 +++

Description of problem:

posix_mknod always sets the value of trusted.pgfid.xxx to 1. This works in most cases but is incorrect when posix_mknod calls posix_create_link_if_gfid_exists.

This leads to problems when renaming a file as the xattr is deleted and the subsequent posix_rename fails.
