in ext4's NFS support, and fix an ioctl (EXT4_IOC_GROUP_ADD) used by old versions of e2fsprogs which we accidentally broke a while back. Also fixed some error paths in ext4's quota and inline data support. Finally, improve tail latency in jbd2's commit code. -----BEGIN PGP SIGNATURE----- iQEzBAABCAAdFiEEK2m5VNv+CHkogTfJ8vlZVpUNgaMFAlwgYYEACgkQ8vlZVpUN gaPh1Af9GCGcgbwmmE+PSwqYXXdDm27hG3Xv4glLcAnmmuT32lMjzjifWPhT8sFs +l1nh2rd0/u14PocjAL8neuuc9G9J+xNS33jlNQsqMsfFQD4cZMk7T1j68JIAEd3 bt/VNIUxvPshYwgvEJlXAeZvXx8kPMKyR44/FyzHdU9oDSWBYE3A9+rjRGUFxXDR LuqwLhvERv6Vykfrzhluj8IOZM6V221alRDuWjx1sQF+/E6zAqyjR3YoYXk04Ajg vnAfEXToeBwLVeTUQgmT9hPrinh7/00wCKekNuzzhg7oKDp7FgD1BMlxBr9eOW+5 pQwM9T+AVbs9EfpYasC6ElEMbLfOPw== =lCnm -----END PGP SIGNATURE----- Merge tag 'ext4_for_linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tytso/ext4 Pull ext4 updates from Ted Ts'o: "All cleanups and bug fixes; most notably, fix some problems discovered in ext4's NFS support, and fix an ioctl (EXT4_IOC_GROUP_ADD) used by old versions of e2fsprogs which we accidentally broke a while back.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
