The xattr remote value set/remove handlers both clear args.trans in the error path without having cancelled the transaction. This leaks the transaction, causes warnings around returning to userspace with locks held and leads to system lockups or other general problems. The higher level xfs_attr_[set|remove]() functions already detect and cancel args.trans when set in the error path. Drop the NULL assignments from the rmtval handlers and allow the callers to clean up the transaction correctly.

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.
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.
