Hello Nikolay,

Nikolay Pertsev:

I don't think it "memory leak."

And the story continued to the next Jan... and Sep 2013 when I
introduced a new logic to trucate XINO files.

For tmpfs, it is enabled automatically.
If you have HDD, then you can specify "xino=/dir/file/on/HDD."
According to past mails, Jacek Konieczny chose "noxino" option.

My recommendation is
- check the size and the number of the consumed blocks of XINO files via
  debugfs and make sure they are big pressure for tmpfs.
- use latest aufs to see the effect of new truncation algorythm
  (implemented in Sep 2013)
- try the mount option "xino=/dir/file/on/HDD" if you can.

The last resort which I don't recommend is "noxino" option.
