Pull bcachefs updates from Kent Overstreet:
- More safety fixes, primarily found by syzbot
- Run the upgrade/downgrade paths in nochnages mode. Nochanges mode is
primarily for testing fsck/recovery in dry run mode, so it shouldn't
change anything besides disabling writes and holding dirty metadata
in memory.
The idea here was to reduce the amount of activity if we can't write
anything out, so that bringing up a filesystem in "super ro" mode
would be more lilkely to work for data recovery - but norecovery is
the correct option for this.
- btree_trans->locked; we now track whether a btree_trans has any btree
nodes locked, and this is used for improved assertions related to
trans_unlock() and trans_relock(). We'll also be using it for

kprobe/ftrace: fix build error due to bad function definition
Commit 1a7d0890dd4a ("kprobe/ftrace: bail out if ftrace was killed")
introduced a bad K&R function definition, which we haven't accepted in a
long long time.
Gcc seems to let it slide, but clang notices with the appropriate error:
kernel/kprobes.c:1140:24: error: a function declaration without a prototype is deprecated in all >
1140 | void kprobe_ftrace_kill()

but this commit was apparently never in linux-next before it was sent
upstream, so it didn't get the appropriate build test coverage.

Pull tracing user-event updates from Steven Rostedt:
- Minor update to the user_events interface
The ABI of creating a user event states that the fields are separated
by semicolons, and spaces should be ignored.
But the parsing expected at least one space to be there (which was
incorrect). Fix the reading of the string to handle fields separated
by semicolons but no space between them.
This does extend the API sightly as now "field;field" will now be
parsed and not cause an error. But it should not cause any regressions
as no logic should expect it to fail.
Note, that the logic that parses the event fields to create the
trace_event works with no spaces after the semi-colon. It is

Pull tracing ring buffer updates from Steven Rostedt:
"Add ring_buffer memory mappings.
The tracing ring buffer was created based on being mostly used with
the splice system call. It is broken up into page ordered sub-buffers
and the reader swaps a new sub-buffer with an existing sub-buffer
that's part of the write buffer. It then has total access to the
swapped out sub-buffer and can do copyless movements of the memory
into other mediums (file system, network, etc).
The buffer is great for passing around the ring buffer contents in the
kernel, but is not so good for when the consumer is the user space
task itself.
A new interface is added that allows user space to memory map the ring
buffer. It will get all the write sub-buffers as well as reader
sub-buffer (that is not written to). It can send an ioctl to change
