[ Upstream commit 249c3a0e53acefc2b06d3b3e1fc28fb2081f878d ]
Place cleanup_module() in .exit.text section. Currently,
cleanup_module() is likely placed in the .text section. It's
inconsistent with the layout of C modules, where cleanup_module() is
placed in .exit.text.
[ Boqun asked for an example of how the section changed to be
put in the log. Tomonori provided the following examples:
C module:
$ objdump -t ~/build/x86/drivers/block/loop.o|grep clean
0000000000000000 l O .exit.data 0000000000000008 __UNIQUE_ID___addressable_cleanup_module412
0000000000000000 g F .exit.text 000000000000009c cleanup_module
Rust module without this patch:
$ objdump -t ~/build/x86/samples/rust/rust_minimal.o|grep clean
00000000000002b0 g F .text 00000000000000c6 cleanup_module
0000000000000000 g O .exit.data 0000000000000008 _R...___UNIQUE_ID___addressable_cleanup_module
Rust module with this patch:
$ objdump -t ~/build/x86/samples/rust/rust_minimal.o|grep clean
0000000000000000 g F .exit.text 00000000000000c6 cleanup_module
0000000000000000 g O .exit.data 0000000000000008 _R...___UNIQUE_ID___addressable_cleanup_module

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.
