[Bug 1234662] [NEW] Ubuntu-lts-3.8.0 kernels corrupt ext[234] filesystems with 1k block size in Xen guests

 

Public bug reported:

We observed a problem with a Postfix database file created by postmap
becoming corrupted in a Xen guest when the file was on an ext4
filesystem with a 1kb block size.  This was reported to the linux-ext4
list in http://marc.info/?t=138018028300003&r=1&w=2.  The subsequent
investigation identified the git commit
7b2b160da7661bb2ade3f924b1bd3e3084e53341 as solving the problem.  We
have applied this on top of tag Ubuntu-lts-3.8.0-13.22 and confirmed
that it resolves the problem we are seeing.
