Christoph Hellwig bda250dbaf xfs: rewrite xfs_dq_get_next_id using xfs_iext_lookup_extent
This goes straight to a single lookup in the extent list and avoids a
roundtrip through two layers that don't add any value for the simple
quoata file that just has data or holes and no page cache, delayed
allocation, unwritten extent or COW fork (which btw, doesn't seem to
be handled by the existing SEEK HOLE/DATA code).

Linux kernel
============

This file was moved to Documentation/admin-guide/README.rst

Please notice that there are several guides for kernel developers and users.
These guides can be rendered in a number of formats, like HTML and PDF.

In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``.

There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
See Documentation/00-INDEX for a list of what is contained in each file.

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.
