Linux kernel source tree

Cong Wang says: ==================== idr: fix overflow cases on 32-bit CPU idr_get_next_ul() is problematic by design, it can't handle the following overflow case well on 32-bit CPU: u32 id = UINT_MAX; idr_alloc_u32(&id); while (idr_get_next_ul(&id) != NULL) id++; when 'id' overflows and becomes 0 after UINT_MAX, the loop goes infinite. Fix this by eliminating external users of idr_get_next_ul() and migrating them to idr_for_each_entry_continue_ul(). And add an additional parameter for these iteration macros to detect overflow properly. Please merge this through networking tree, as all the users are in networking subsystem. ==================== Signed-off-by: David S. Miller <davem@davemloft.net> |

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.
