Except 'current' is still on 3.18.11 and as I said above, it looks like this latest 3.18.14 will introduce the problem commit.
There's still the two ext4 issues, but from the look of them they're both fairly long standing and much harder to trigger.
@moisespedro: assuming this is the same bug, I suggest that you modify this thread's title that could be:as it probably doesn't affect only ext4 file systems.
I am referring to this message from Holger Kiehl on LKML.
Also, at time of writing according to this comment from Eric Work the fix for this bug has been merged into Linus' tree as commit a81157768a00e8cf8a7b43b5ea5cac931262374f but that doesn't mean that the 4.0 branch has been fixed.
But if it's not actually the same problem, then being aware of both is a good thing...
Thanks Didier, I've tried to change the title but I am still confused if I got it right.
This is the patch that is already incorporated in 3.18.14, see changelog. The one that is missing is the fix for the corruption occurring with Raid0 (which might have gotten introduced by another patch specific to 3.8.14).

I didn't pay enough attention, thank you for accuracy.
If I understand right, it's something about RAIDOs running in SSDs. So, we shouldn't be affected.
Really, if for you, the SSD is not fast enough and you go RAID0 for your important data or OS, seems that you like to live dangerously, very dangerously...

I don't think RAID0 is that unsafe. At least if no bug like this occurs. I still have 2 Hitachi HDT72503's in RAID0. I have these drives for at least 12 years and they never been formatted after I installed them. Never ever had a problem. I've migrated from Windows XP to 7 to 8.1 without formatting it. Files I copied to the drive 12 years ago still work today.

Yet, when one of your hard disks will go south, you'll lost all data, instead of half of the amount...
And the hard disks are the firsts on your system who go south, usually. Combined with those shiny SSDs, who aren't typically made for a century long life, I consider that that combination is similar with looking for gas leak with a lighter...
