ext4 not updating ctime on truncate ?

[Badari Pulavarty <pbadari@gmail.com>]

Hi,

I ran Linux POSIX filesystem test suite released by  Szabolcs Szakacsits
on ext4. I get one failure on ext4.

Failed Test                     Stat Wstat Total Fail  Failed  List of
Failed
-------------------------------------------------------------------------------
/root/posix/tests/truncate/00.t               21    1   4.76%  15

Looking at the test, its complaining that ext4 is not updating ctime
for truncate. Is this a known issue ?

# successful truncate(2) updates ctime.
expect 0 create ${n0} 0644
ctime1=`${fstest} stat ${n0} ctime`
sleep 1
expect 0 truncate ${n0} 123
ctime2=`${fstest} stat ${n0} ctime`
test_check $ctime1 -lt $ctime2


Thanks,
Badari
