Existing code forces/assume args to type "long" which won't work in LP64 regime, so prepare code for that Interestingly this should be a non functional change but I do see some codegen changes | bloat-o-meter vmlinux-cmpxchg-A vmlinux-cmpxchg-B | add/remove: 0/0 grow/shrink: 17/12 up/down: 218/-150 (68) | | Function old new delta | rwsem_optimistic_spin 518 550 +32 | rwsem_down_write_slowpath 1244 1274 +30 | __do_sys_perf_event_open 2576 2600 +24 | down_read 192 200 +8 | __down_read 192 200 +8 ... | task_work_run 168 148 -20 | dma_fence_chain_walk.part 760 736 -24 | __genradix_ptr_alloc 674 646 -28 Total: Before=6187409, After=6187477, chg +0.00% Acked-by: Peter Zijlstra (Intel) <peterz@infradead.org> Signed-off-by: Vineet Gupta <vgupta@kernel.org>
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.
