Currently, we are using IDA library for managing IDs on a FlexRM ring. The IDA library dynamically allocates memory for underlying data structures which can cause potential locking issue when allocating/free IDs from flexrm_new_request() and flexrm_process_completions(). To tackle this, we replace use of IDA with bitmap for each FlexRM ring and also protect the bitmap with FlexRM ring lock.

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. 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.
