So, the basic things I can think of to test here are:
1. The kernel can still load the previous MODVERSIONS format
2. The kernel can load the new MODVERSIONS format
3. If we artificially tweak a CRC in the previous format, it will fail to load.
4. If we artificially tweak a CRC in the new format,
The new version info format has a superset of symbols in the old format.
Since this is a tool for in-tree modules, we don't need to parse the old
one with this tool any longer.

the `.mod.c` file. Their presence in the final m

Currently, `export_report.pl` will error out if it sees a hex number not

This is prepwork for the subsequ

The `export_report.pl` script was broken [1] a while back due to a code

This patch series is intended for use alongside the Implement
MODVERSIONS for RUST [1] series as a replacement for the symbol name
hashing approach used there to enable RUST and MODVERSIONS at the same

Using commas to declare struct members makes adding new members to this

1. Previously, we did not validate non-SHF_ALLOC sections.

Test to check if setting PROC_CN_MCAST_NOTIFY in proc connector API, allows
a thread's non-zero exit status to be returned to proc_filter.
The threads.c program creates 2 child threads. 1st thread handles signal
SIGSEGV, and 2nd thread needs to indicate some error condition (value 1)
to the kernel
Kunit tests to test hash table add, delete, duplicate add and delete.
Add following configs and compile kernel code:
CONFIG_CONNECTOR=y
CONFIG_PROC_EVENTS=y
CONFIG_NET=y
CONFIG_KUNIT=m
CONFIG_CN_HASH_KUNIT_TEST=m
To run kunit tests:
sudo modprobe cn_hash_test
Output of kunit tests and hash table
Add a new type PROC_CN_MCAST_NOTIFY to proc connector API, which allows a
thread to notify the kernel that is going to exit with a non-zero exit
code and specify the exit code in it. When thread exits in the kernel,
it will send this exit code as a proc filter notification to any
listening process.
Recently we committed a fix to allow processes to receive notifications for
non-zero exits via the process connector module. Commit is a4c9a56e6a2c.
However, for threads, when it does a pthread_exit(&exit_status) call, the
kernel is not aware of the exit status with which pthread_exit is called.

This patch corrects typographical errors in the "name" fields of
the JSON objects with IDs "4319" and "4341" in the tc-testing
selftests.
- "diffferent" is corrected to "different".
- "muliple" is corrected to "multiple".

This commit adds an rcutorture.reader_flavor parameter whose bits
correspond to reader flavors. For example, SRCU's readers are 0x1 for
normal and 0x2 for NMI-safe.

This commit moves __srcu_read_lock_lite() and __srcu_read_unlock_lite()
into include/linux/srcu.h and marks them "static inline" so that they
can be inlined into srcu_read_lock_lite() and srcu_read_unlock_lite(),
respectively. They are not hand-inlined due to Tree SRCU and Tiny SRCU

This commit adds an rcutorture scenario that tests light-weight SRCU
readers. While in the area, it adjusts the size of the TREE10 scenario.
