Description

Updated kernel-linus fixes security, critical data corruption and pdata loss issues

This kernel-linus update is based on upstream -longterm 3.14.43 and fixes
a security issue, and critical data corruption and data loss issues:

drivers/vhost/scsi.c: potential memory corruption (CVE-2015-4036)

ext4 filesystem has a bug that make it possible to lose whole file system
block worth of data when we hit the specific interaction with unwritten
and delayed extents in status extent tree.

when using software raid 0 on SSDs along with trim/discard, any delete or
modification of files can lead to random destruction on the filesystem.
(this regression was introduced in upstream 3.14.41)
