I noticed a couple of commits regarding btrfs. Can anybody summarize them to someone that doesn't know anything about kernels and very little about file systems

  The big improvements to btrfs came in 3.12. The 3.13 changes are rather minor: a mount option to specify the maximum delay before committing writes to storage (default 30 seconds, no maximum, warning for 300+ seconds -- make sure you have battery coverage for whatever this is set to plus a few seconds, and try not to crash...) a mount option for emergency use that will force the rebuild of the UUID tree userspace tools that read FIEMAP_EXTENT_SHARED can now use that on btrfs; no functionality change, really, just making the info available in the same way that ocfs2 does it.
