All these have been in linux-next with no reported issues.

Pull more bcachefs updates from Kent Overstreet:
"Here's the second big bcachefs pull request. This brings your tree up
to date with my master branch, which is what existing bcachefs users
are currently running.

New features:
- rebalance_work btree (and metadata version 1.3): the rebalance
thread no longer has to scan to find extents that need processing -
big scalability improvement.
- sb_errors superblock section: this adds counters for each fsck
error type, since filesystem creation, along with the date of the
most recent error. It'll get us better bug reports (since users do
not typically report errors that fsck was able to fix), and I might
add telemetry for this in the future.

Fixes include:
- multiple snapshot deletion fixes
- members_v2 fixups
- deleted_inodes btree fixes
- copygc thread no longer spins when a device is full but has no
fragmented buckets (i.e. rebalance needs to move data around
instead)
- a fix for a memory reclaim issue with the btree key cache: we're
now careful not to hold the srcu read lock that blocks key cache
reclaim for too long
- an early allocator locking fix, from Brian
- endianness fixes, from Brian
- CONFIG_BCACHEFS_DEBUG_TRANSACTIONS no longer defaults to y, a big
performance improvement on multithreaded workloads"

bcachefs: rebalance_work

This adds a new btree, rebalance_work, to eliminate scanning required
for finding extents that need work done on them in the background - i.e.
for the background_target and background_compression options.

rebalance_work is a bitset btree, where a KEY_TYPE_set corresponds to an
extent in the extents or reflink btree at the same pos.

A new extent field is added, bch_extent_rebalance, which indicates that
this extent has work that needs to be done in the background - and which
options to use. This allows per-inode options to be propagated to
indirect extents - at least in some circumstances. In this patch,
changing IO options on a file will not propagate the new options to
indirect extents pointed to by that file.

Updating (setting/clearing) the rebalance_work btree is done by the
extent trigger, which looks at the bch_extent_rebalance field.

Scanning is still requrired after changing IO path options - either just
for a given inode, or for the whole filesystem. We indicate that
scanning is required by adding a KEY_TYPE_cookie key to the
rebalance_work btree: the cookie counter is so that we can detect that
scanning is still required when an option has been flipped mid-way
through an existing scan.

Future possible work:
- Propagate options to indirect extents when being changed
- Add other IO path options - nr_replicas, ec, to rebalance_work so
they can be applied in the background when they change
- Add a counter, for bcachefs fs usage output, showing the pending
amount of rebalance work: we'll probably want to do this after the
disk space accounting rewrite (moving it to a new btree)

bcachefs: Persist 64 bit io clocks

Originally, bcachefs - going back to bcache - stored, for each bucket, a
16 bit counter corresponding to how long it had been since the bucket
was read from. But, this required periodically rescaling counters on
every bucket to avoid wraparound. That wasn't an issue in bcache, where
we'd perodically rewrite the per bucket metadata all at once, but in
bcachefs we're trying to avoid having to walk every single bucket.

This patch switches to persisting 64 bit io clocks, corresponding to the
64 bit bucket timestaps introduced in the previous patch with
KEY_TYPE_alloc_v2.
