Description

It appears that lustre_rsync is unable to replicate new files and dirs i nthe root od new filesystem
The check for deleted files triggers like this:

***** Start 22 MKDIR (2) [0x200000400:0xa:0x0] [0x80001:0xd9558f05:0x0] aaa *****
dest = /aaa; savedpath = aaa                                            <----------------------------------------------------------------------- HERE!
create: file moved ([0x200000400:0xa:0x0]). /aaa != aaa
mkfile(2) /mnt/st04fs/.lustrerepl/[0x200000400:0xa:0x0] 

Reproducer is simple
enable changelogs, create /src/dir run lustre_rsync from /src to /dst and see how /dst/dir is not created, but instead there's a dir with a fid name in /dst/.lustrerepl
