Hi Zoltán and all,

I _was_ testing the patch series (the latest version), system worked
OK for two days, but then I got a system crash (probably hardware
related) and lost my files in the main partition. Posted about it in
the F2FS mailing list
(https://sourceforge.net/p/linux-f2fs/mailman/message/35928135/).

While I don't believe that the freeze/crash was caused by the watchdog
driver (many other things to blame: amdgpu driver on Southern Islands,
CPU voltage lower than recommended...), it's worth mentioning that the
computer was completely frozen for a little over 4 minutes, and did
not reset as I'd expect the watchdog to. Just mentioning because I'm
not sure of the implications.

Once I get my system back online this weekend I'll have a good look at
the code. Anyway, thanks again for the patches and I'm also expecting
someone more qualified (than me, at least) to review them.

Regards
Marcelo "Marc" Ranolfi
