Unlike qgroup rescan, which always shows whether it cleared the inconsistent flag, we do not have a proper way to show if qgroup is marked inconsistent. This was not a big deal before as there aren't that many locations that can mark qgroup inconsistent. But with the introduction of drop_subtree_threshold, qgroup can be marked inconsistent very frequently, especially when dropping subvolumes. Although most user space tools relying on qgroup should do their own checks and queue a rescan if needed, we have no idea when qgroup is marked inconsistent, and this would be much harder to debug. So this patch will add an extra warning (btrfs_warn_rl()) when the qgroup flag is flipped into inconsistent for the first time. And add extra reason why qgroup flips inconsistent. This means we can move the error message immediately before qgroup_inconsistent_warning() into that function. For call sites without an obvious reason, or is a shared error handling, output the function that failed and the error code instead.

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 reStructuredText 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.
