[LU-3620] missing CLF_RENAME_LAST flag in CL_RENME record

Fri, 23 Aug 2013 23:05:24 +0000

CLF_RENAME_LAST flag is supposed to be set in RENME changelog record
if the rename operation unlinks the target.

The following reproducer shows this is not the case in lustre 2.4.0:

touch /mnt/lustre/foo
touch /mnt/lustre/bar
mv /mnt/lustre/foo /mnt/lustre/bar
mv: overwrite `/mnt/lustre/bar'? yes

RENME flag is 0x0, should be 0x01.

The flag was still correct on lustre 2.3.0:
6 08RENME 13:33:51.820025792 2013.07.23 0x1 t=[0x200000400:0x2:0x0] p=[0x61ab:0x4710a859:0x0] bar s=[0x200000400:0x1:0x0] sp=[0x61ab:0x4710a859:0x0] foo
