Directory tree repairs are the least complete part of online fsck, due
to the lack of directory parent pointers. However, even without that
feature, we can still make some corrections to the directory tree -- we
can salvage as many directory entries as we can from a damaged
directory, and we can reattach orphaned inodes to the lost+found, just
as xfs_repair does now.

File-based metadata (such as xattrs and directories) can be extremely
large. To reduce the memory requirements and maximize code reuse, it is
very convenient to create a temporary file, use the regular dir/attr
code to store salvaged information, and then atomically swap the extents
between the file being repaired and the temporary file. Record the high
level concepts behind how temporary files and atomic content swapping
should work, and then present some case studies of what the actual
repair functions do.

Certain parts of the online fsck code need to scan every file in the
entire filesystem. It is not acceptable to block the entire filesystem
while this happens, which means that we need to be clever in allowing
scans to coordinate with ongoing filesystem updates. We also need to
hook the filesystem so that regular updates propagate to the staging
records.

Add a discussion of the btree bulk loading code, which makes it easy to
take an in-memory recordset and write it out to disk in an efficient
manner. This also enables atomic switchover from the old to the new
structure with minimal potential for leaking the old blocks.

Writes to an XFS filesystem employ an eventual consistency update model
to break up complex multistep metadata updates into small chained
transactions. This is generally good for performance and scalability
because XFS doesn't need to prepare for enormous transactions, but it
also means that online fsck must be careful not to attempt a fsck action
unless it can be shown that there are no other threads processing a
transaction chain. This part of the design documentation covers the
thinking behind the consistency model and how scrub deals with it.

When driver doesn't implement a bpf_xdp_metadata kfunc the fallback
implementation returns EOPNOTSUPP, which indicate device driver doesn't
implement this kfunc.
Currently many drivers also return EOPNOTSUPP when the hint isn't
available, which is ambiguous from an API point of view. Instead
change drivers to return ENODATA in these cases.
There can be natural cases why a driver doesn't provide any hardware
info for a specific hint, even on a frame to frame basis (e.g. PTP).
Lets keep these cases as separate return codes.
When describing the return values, adjust the function kernel-doc layout
to get proper rendering for the return values.

I relicensed Netlink spec code to GPL-2.0 OR BSD-3-Clause but
we still put a slightly different license on the uAPI header
than the rest of the code. Use the Linux-syscall-note on all
the specs and all generated code. It's moot for kernel code,
but should not hurt. This way the licenses match everywhere.

Jiri Kosina, Jonathan Corbet, and Willy Tarreau all expressed a desire
to move this document under process/.
Create a new section for security issues in the index and group it with
embargoed-hardware-issues.
I'm doing this at the start of the series to make all the subsequent
changes show up in 'git blame'.
Existing references were updated using:
git grep -l security-bugs ':!Documentation/translations/' | xargs sed -i 's|admin-guide/security-bugs|process/security-bugs|g'
git grep -l security-bugs Documentation/translations/ | xargs sed -i 's|Documentation/admin-guide/security-bugs|Documentation/process/security-bugs|g'
git grep -l security-bugs Documentation/translations/ | xargs sed -i '/Original:/s|\.\./admin-guide/security-bugs|\.\./process/security-bugs|g'
Notably, the page is not moved in the translations (due to my lack of
knowledge of these languages), but the translations have been updated
to point to the new location of the original document where these
references exist.

I was intending to make all the Netlink Spec code BSD-3-Clause
to ease the adoption but it appears that:
- I fumbled the uAPI and used "GPL WITH uAPI note" there
- it gives people pause as they expect GPL in the kernel
As suggested by Chuck re-license under dual. This gives us benefit
of full BSD freedom while fulfilling the broad "kernel is under GPL"
expectations.
