Linux kernel source tree
3809db6430
Although snd_rawmidi_drain_output() may take some long time, it has no protection and intrusive operations like the buffer resize may happen meanwhile. For making the operation a bit more robust, this patch takes the buffer refcount for blocking the buffer resize. Also, as this function is exported, in theory, it might be called asynchronously from the stream open/close state. For avoiding the missing refcount, now the close call checks the buffer refcount, too.

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.
