  ext4: fix spelling mistake: "prellocated" -> "preallocated" (2017-07-06 15:28:45 -0400)

The first major feature for ext4 this merge window is the largedir
feature, which allows ext4 directories to support over 2 billion
directory entries (assuming ~64 byte file names; in practice, users
will run into practical performance limits first.)  This feature was
originally written by the Lustre team, and credit goes to Artem
Blagodarenko from Seagate for getting this feature upstream.

The second major major feature allows ext4 to support extended
attribute values up to 64k.  This feature was also originally from
Lustre, and has been enhanced by Tahsin Erdogan from Google with a
deduplication feature so that if multiple files have the same xattr
value (for example, Windows ACL's stored by Samba), only one copy will
be stored on disk for encoding and caching efficiency.

We also have the usual set of bug fixes, cleanups, and optimizations.
