io_uring: for requests that require async, force it

Some requests require being run async as they do not support
non-blocking. Instead of trying to issue these requests, getting -EAGAIN
and then queueing them for async issue, rather just force async upfront.

Add WARN_ON_ONCE to make sure surprising code paths do not come up,
however in those cases the bug would end up being a blocking
io_uring_enter(2) which should not be critical.

Merge tag 'fs.idmapped.mnt_idmap.v6.2' of git://git.kernel.org/pub/scm/linux/kernel/git/vfs/idmapping

Pull idmapping updates from Christian Brauner:
"Last cycle we've already made the interaction with idmapped mounts
more robust and type safe by introducing the vfs{g,u}id_t type. This
cycle we concluded the conversion and removed the legacy helpers.

Currently we still pass around the plain namespace that was attached
to a mount. This is in general pretty convenient but it makes it easy
to conflate namespaces that are relevant on the filesystem - with
namespaces that are relevent on the mount level. Especially for
filesystem developers without detailed knowledge in this area this can
be a potential source for bugs.

Instead of passing the plain namespace we introduce a dedicated type
struct mnt_idmap and replace the pointer with a pointer to a struct
mnt_idmap. There are no semantic or size changes for the mount struct
caused by this.

We then start converting all places aware of idmapped mounts to rely
on struct mnt_idmap. Once the conversion is done all helpers down to
the really low-level make_vfs{g,u}id() and from_vfs{g,u}id() will take
a struct mnt_idmap argument instead of two namespace arguments. This
way it becomes impossible to conflate the two removing and thus
eliminating the possibility of any bugs. Fwiw, I fixed some issues in
that area a while ago in ntfs3 and ksmbd in the past. Afterwards only
low-level code can ultimately use the associated namespace for any
permission checks. Even most of the vfs can be completely obivious
about this ultimately and filesystems will never interact with it in
any form in the future.

A struct mnt_idmap currently encompasses a simple refcount and pointer
to the relevant namespace the mount is idmapped to. If a mount isn't
idmapped then it will point to a static nop_mnt_idmap and if it
doesn't that it is idmapped. As usual there are no allocations or
anything happening for non-idmapped mounts. Everthing is carefully
written to be a nop for non-idmapped mounts as has always been the
case.

If an idmapped mount is created a struct mnt_idmap is allocated and a
reference taken on the relevant namespace. Each mount that gets
idmapped or inherits the idmap simply bumps the reference count on
struct mnt_idmap. Just a reminder that we only allow a mount to change
it's idmapping a single time and only if it hasn't already been
attached to the filesystems and has no active writers.

The actual changes are fairly straightforward but this will have huge
benefits for maintenance and security in the long run even if it
causes some churn.

Note that this also makes it possible to extend struct mount_idmap in
the future. For example, it would be possible to place the namespace
pointer in an anonymous union together with an idmapping struct. This
would allow us to expose an api to userspace that would let it specify
idmappings directly instead of having to go through the detour of
setting up namespaces at all"

acl: conver higher-level helpers to rely on mnt_idmap
fs: introduce dedicated idmap type for mounts
