While the old code did support FSCONFIG_SET_FD, there's no need to

If you pass an fd using FSCONFIG_SET_FD, autofs_parse_fd() "steals" the
param->file and so the fs_context infrastructure will not do fput() for
us.

When deactivating any type of superblock, it had to wait for the in-flight
wb switches to be completed. wb switches are executed in inode_switch_wbs_work_fn()
which needs to acquire the wb_switch_rwsem and races against sync_inodes_sb().
If there are too much dirty data in the superblock, the waiting time may increase
significantly.
For superblocks without cgroup writeback such as tmpfs, they have nothing to
do with the wb swithes, so the flushing can be avoided.

Christian Brauner <brauner@kernel.org> says:
Systemd has a helper called openat_report_new() that returns whether a
file was created anew or it already existed before for cases where
O_CREAT has to be used without O_EXCL (cf. [1]). That apparently isn't
something that's specific to systemd but it's where I noticed it.
The current logic is that it first attempts to open the file without
O_CREAT | O_EXCL and if it gets ENOENT the helper tries again with both
flags. If that succeeds all is well. If it now reports EEXIST it
retries.
That works fairly well but some corner cases make this more involved. If
this operates on a dangling symlink the first openat() without O_CREAT |
O_EXCL will return ENOENT but the second openat() with O_CREAT | O_EXCL
will fail with EEXIST. The reason is that openat() without O_CREAT |
O_EXCL follows the symlink while O_CREAT | O_EXCL doesn't for security
reasons. So it's not something we can really change unless we add an
explicit opt-in via O_FOLLOW which seems really ugly.
The caller could try and use fanotify() to register to listen for
creation events in the directory before calling openat(). The caller
could then compare the returned tid to its own tid to ensure that even
in threaded environments it actually created the file. That might work
but is a lot of work for something that should be fairly simple and I'm
uncertain about it's reliability.
The caller could use a bpf lsm hook to hook into security_file_open() to
figure out whether they created the file. That also seems a bit wild.
So let's add F_CREATED_QUERY which allows the caller to check whether
they actually did create the file. That has caveats of course but I
don't
think they are problematic:
* In multi-threaded environments a thread can only be sure that it did
create the file if it calls openat() with O_CREAT. In other words,
it's obviously not enough to just go through it's fdtable and check
these fds because another thread could've created the file.
* If there's any codepaths where an openat() with O_CREAT would yield
the same struct file as that of another thread it would obviously
cause wrong results. I'm not aware of any such codepaths from openat()
itself. Imho, that would be a bug.
* Related to the previous point, calling the new fcntl() on files created
and opened via special-purpose system calls or ioctl()s would cause
wrong results only if the affected subsystem a) raises FMODE_CREATED
and b) may return the same struct file for two different calls. I'm
not seeing anything outside of regular VFS code that raises
FMODE_CREATED.
There is code for b) in e.g., the drm layer where the same struct file
is resurfaced but again FMODE_CREATED isn't used and it would be very
misleading if it did.

fuse_notify_store(), unlike fuse_do_readpage(), does not enable page
zeroing (because it can be used to change partial page contents).
So fuse_notify_store() must be more careful to fully initialize page
contents (including parts of the page that are beyond end-of-file)
before marking the page uptodate.
The current code can leave beyond-EOF page contents uninitialized, which
makes these uninitialized page contents visible to userspace via mmap().
This is an information leak, but only affects systems which do not
enable init-on-alloc (via CONFIG_INIT_ON_ALLOC_DEFAULT_ON=y or the
corresponding kernel command line parameter).

Pull bcachefs fixes from Kent OverstreetL
- New on disk format version, bcachefs_metadata_version_disk_accounting_inum
This adds one more disk accounting counter, which counts disk usage
and number of extents per inode number. This lets us track
fragmentation, for implementing defragmentation later, and it also
counts disk usage per inode in all snapshots, which will be a useful
thing to expose to users.
- One performance issue we've observed is threads spinning when they
should be waiting for dirty keys in the key cache to be flushed by
journal reclaim, so we now have hysteresis for the waiting thread, as
well as improving the tracepoint and a new time_stat, for tracking
time blocked waiting on key cache flushing.

Although there are several patches improving the extent map shrinker,
there are still reports of too frequent shrinker behavior, taking too
much CPU for the kswapd process.
So let's only enable extent shrinker for now, until we got more
comprehensive understanding and a better solution.

Pull rust fixes from Miguel Ojeda:
- Fix '-Os' Rust 1.80.0+ builds adding more intrinsics (also tweaked in
upstream Rust for the upcoming 1.82.0).
- Fix support for the latest version of rust-analyzer due to a change
on rust-analyzer config file semantics (considered a fix since most
developers use the latest version of the tool, which is the only one
actually supported by upstream). I am discussing stability of the
config file with upstream -- they may be able to start versioning it.
- Fix GCC 14 builds due to '-fmin-function-alignment' not skipped for
libclang (bindgen).
- A couple Kconfig fixes around '{RUSTC,BINDGEN}_VERSION_TEXT' to
suppress error messages in a foreign architecture chroot and to use a
proper default format.
- Clean 'rust-analyzer' target warning due to missing recursive make
invocation mark.
- Clean Clippy warning due to missing indentation in docs.
- Clean LLVM 19 build warning due to removed 3dnow feature upstream.
