Subject: [PATCH] main: force timeout 0 for ovl_link
There is an issue on RHEL 8.1 where the nlink counter is always
incremented by one, no matter what is specified in e.attr.st_nlink.
Always set timeout to 0 to force a new stat on the inode.
Closes: https://bugzilla.redhat.com/show_bug.cgi?id=1802907
