Pull xfs updates from Carlos Maiolino:
"This contains several improvements to zoned device support,
performance improvements for the parent pointers, and a new health
monitoring feature. There are some improvements in the journaling code
too but no behavior change expected.

Last but not least, some code refactoring and bug fixes are also
included in this series"

xfs: autonomous self healing of filesystems [v7]

This patchset builds new functionality to deliver live information about
filesystem health events to userspace. This is done by creating an
anonymous file that can be read() for events by userspace programs.
Events are captured by hooking various parts of XFS and iomap so that
metadata health failures, file I/O errors, and major changes in
filesystem state (unmounts, shutdowns, etc.) can be observed by
programs.

When an event occurs, the hook functions queue an event object to each
event anonfd for later processing. Programs must have CAP_SYS_ADMIN
to open the anonfd and there's a maximum event lag to prevent resource
overconsumption. The events themselves can be read() from the anonfd
as C structs for the xfs_healer daemon.

In userspace, we create a new daemon program that will read the event
objects and initiate repairs automatically. This daemon is managed
entirely by systemd and will not block unmounting of the filesystem
unless repairs are ongoing. They are auto-started by a starter
service that uses fanotify.

This patchset depends on the new fserror code that Christian Brauner
has tentatively accepted for Linux 7.0:
https://git.kernel.org/pub/scm/linux/kernel/git/vfs/vfs.git/log/?h=vfs-7.0.fserror

v7: more cleanups of the media verification ioctl, improve comments, and
reuse the bio
v6: fix pi-breaking bugs, make verify failures trigger health reports
and filter bio status flags better
v5: add verify-media ioctl, collapse small helper funcs with only
one caller
v4: drop multiple client support so we can make direct calls into
healthmon instead of chasing pointers and doing indirect calls
v3: drag out of rfc status

With a bit of luck, this should all go splendidly.

Conflicts:
This merge required an update on files:
- fs/xfs/xfs_healthmon.c
- fs/xfs/xfs_verify_media.c
Such change was required because a parallel developement changed
XFS header file xfs.h naming to xfs_platform.h, so the merge
required to update those includes in both files above
