Linus Torvalds cfb82e1df8 y2038: add inode timestamp clamping
This series from Deepa Dinamani adds a per-superblock minimum/maximum
 timestamp limit for a file system, and clamps timestamps as they are
 written, to avoid random behavior from integer overflow as well as having
 different time stamps on disk vs in memory.
 
 At mount time, a warning is now printed for any file system that can
 represent current timestamps but not future timestamps more than 30
 years into the future, similar to the arbitrary 30 year limit that was
 added to settimeofday().
 
 This was picked as a compromise to warn users to migrate to other file
 systems (e.g. ext4 instead of ext3) when they need the file system to
 survive beyond 2038 (or similar limits in other file systems), but not
 get in the way of normal usage.
