Most callers of xfs_rmap_lookup_le will retrieve the btree record immediately if the lookup succeeds. The overlapped version of this function (xfs_rmap_lookup_le_range) will return the record if the lookup succeeds, so make the regular version do it too. Get rid of the useless len argument, since it's not part of the lookup key. Signed-off-by: Darrick J.

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.
