This patch drops additionally the sock_mutex when there is a sending message burst. Since we have acknowledge handling we free sending buffers only when we receive an ack back, but if we are stuck in send_to_sock() looping because dlm sends a lot of messages and we never leave the loop the sending buffer fill up very quickly. We can't receive during this iteration because the sock_mutex is held. This patch will unlock the sock_mutex so it should be possible to receive messages when a burst of sending messages happens. This will allow to free up memory because acks which are already received can be processed. Signed-off-by: Alexander Aring <aahringo@redhat.com> Signed-off-by: David Teigland <teigland@redhat.com>
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.
