commitf0b444b349upstream. In function sweep_bh_for_rgrps, which is a helper for punch_hole, it uses variable buf_in_tr to keep track of when it needs to commit pending block frees on a partial delete that overflows the transaction created for the delete. The problem is that the variable was initialized at the start of function sweep_bh_for_rgrps but it was never cleared, even when starting a new transaction. This patch reinitializes the variable when the transaction is ended, so the next transaction starts out with it cleared.

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.
