While chasing a bug involving invalid extent size hints being propagated into newly created realtime files, I noticed that the xfs_ioctl_setattr checks for the extent size hints weren't the same as the ones now encoded in libxfs and used for validation in repair and mkfs. Because the checks in libxfs are more stringent than the ones in the ioctl, it's possible for a live system to set inode flags that immediately result in corruption warnings. Specifically, it's possible to set an extent size hint on an rtinherit directory without checking if the hint is aligned to the realtime extent size, which makes no sense since that combination is used only to seed new realtime files. Replace the open-coded and inadequate checks with the libxfs verifier versions and update the code comments a bit. 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.
