A recent patch to btrfs showed that there was at least 1 case where a nested transaction was committed. Nested transaction in this case means a code which has a transaction handle calls some function which in turn obtains a copy of the same transaction handle. In such cases the correct thing to do is for the lower callee to call btrfs_end_transaction which contains appropriate checks so as to not commit the transaction which will result in stale trans handler for the caller. To catch such cases add an assert in btrfs_commit_transaction ensuring btrfs_trans_handle::use_count is always 1.

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.
