People have been asking to see the plan for this, so -

bcachefs has various background tasks that need to be scheduled to
balance efficiency, predictability of performance, etc.

The design and philosophy hasn't changed too much since bcache, which
was primarily designed for server usage, with sustained load in mind.

These days we're seeing more desktop usage - where we really want to let
the system idle effictively, to reduce total power usage - while also
still balancing previous concerns, we still want to let work accumulate
to a degree.

This lays out all the requirements and starts to sketch out the
algorithm I have in mind.

We can't go RW if it's an image file that hasn't been resized.

Signed-off-by: Kent Overstreet <kent.overstreet@linux.dev>

If a filesystem is going to only be used read-only, and will be a
deployable image, we can strip out alloc info for a substantial
reduction in metadata size - around half, due to backpointers.

Alloc info will be regenerated on first read-write mount.

Remounting RW is disallowed for now, since we don't yet have
check_allocations running in RW mode.

If the root inode/subvolume is unreadable we can repair automatically -
but only if we're still in recovery, so that we can rewind to the
appropriate recovery pass.

Signed-off-by: Kent Overstreet <kent.overstreet@linux.dev>

Instead of going emegency read only with a bch2_fs_inconsistent() call,
log the error and recovery pass appropriately.

If we're still in recovery it'll be repaired immediately, otherwise
it'll be repaired on the next mount.

bch2_print_string_as_lines() is a low level helper that allows messages
longer than 1k to be printed without truncation.

But we should always be printing with the helpers that take a filesystem
object, if we're in fsck they direct output to the userspace process
controlling fsck instead of the dmesg log.

Part of the ongoing project to kill off bch2_(fs|trans)_inconsistent
calls - they generally need to be replaced with either

- a fsck_err() call that can repair the error, or

- logging an error of the appropriate type in the superblock, and
  flagging the appropriate recovery pass to repair the error
