Tested-by retracted temporarily. There's a bug in rename handling. If you
clone:
http://git.infradead.org/users/dhowells/unionmount-testsuite.git
and check out the switch-to-python branch and do:
./run --no rename-mass
then this works with no unioning used, but if you do:
./run --ov rename-mass
to run it on overlayfs, then the following occurs:
[root@andromeda union-testsuite]# ./run --ov rename-mass
***
*** ./run --ov --ts=0 rename-mass
***
TEST rename-mass.py:15: Mass rename sequential files into each other's vacated name slots
./run --rename /mnt/a/foo103 /mnt/a/foo104
./run --rename /mnt/a/foo102 /mnt/a/foo103
./run --rename /mnt/a/foo101 /mnt/a/foo102
./run --rename /mnt/a/foo100 /mnt/a/foo101
./run --rename /mnt/a/foo104 /mnt/a/foo105
/mnt/a/foo104: File unexpectedly found
strace shows:
rename("/mnt/a/foo104", "/mnt/a/foo105") = 0
lstat("/mnt/a/foo104", {st_mode=S_IFREG|0644, st_size=12, ...}) = 0
which shouldn't happen.
The kernel is 17eb601eb5dbc8a2e200872380c03400813d4f1a from overlayfs.v22.
