Protect re-using the same timestamp buffer record before actually adding it to the to interrupt wait list. Mark ts buff offset as in use in the spinlock protection area of the interrupt wait list to avoid getting in the re-use section in ts_buff_get_kernel_ts_record before adding the node to the list. this scenario might happen when multiple threads are racing on same offset and one thread could set data in the ts buff in ts_buff_get_kernel_ts_record then the other thread takes over and get to ts_buff_get_kernel_ts_record and we will try to re-use the same ts buff offset then we will try to delete a non existing node from the list.

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.
