The current vsock code for removal of socket from the list is both subject to race and inefficient. It takes the lock, checks whether the socket is in the list, drops the lock and if the socket was on the list, deletes it from the list. This is subject to race because as soon as the lock is dropped once it is checked for presence, that condition cannot be relied upon for any decision. It is also inefficient because if the socket is present in the list, it takes the lock twice. Signed-off-by: Sunil Muthuswamy <sunilmut@microsoft.com> Signed-off-by: David S.

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.
