Re: Uploading linux (3.16.7-ckt11-1)

I'm not sure where to find the fixes already included with the package
you plan to upload soon, but there is one important fix missing
according to the changelog you included with your mail. AIUI, the data
corruption caused by unwritten and delayed extents is a different issue.
3.16.7-ckt11, like many other recent stable kernel updates, includes the
patch
"md/raid0: fix bug with chunksize not a power of 2."
which causes wrong files to be TRIMmed when enabling discard or running
fstrim on a raid0 setup. That is, random files are suddenly filled with
zeroes instead of their original content when deleting files from the
file system.
This has already caused severe data loss on various Arch systems, and
probably Fedora too. Ubuntu have reverted that patch for their -ckt11
upload to utopic. There is now a patch fixing the regression in Linus'
tree, but not in -ckt11.
See kernel bugzilla:
https://bugzilla.kernel.org/show_bug.cgi?id=98501
Debian bug report (cloned from the delayed extents issue):
https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=786372
I'm sorry for the noise if your package already includes that patch (or
reverts the chunksize-not-a-power-of-2-patch). Thanks for maintaining
the Debian kernel!
