bcachefs: Assert that we're not violating key cache coherency rules

We're not allowed to have a dirty key in the key cache if the key

cache, so that iteration over the btree can check if the key is present
in the key cache.

Things break in subtle ways if cache coherency is broken, so this needs
an assert.

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

bcachefs: Simplify option logic in rebalance

Since bch2_move_get_io_opts() now synchronizes io_opts with options from
bch_extent_rebalance, delete the ad-hoc logic in rebalance.c that
previously did this.

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

bcachefs: get_update_rebalance_opts()

bch2_move_get_io_opts() now synchronizes options loaded from the
filesystem and inode (if present, i.e. not walking the reflink btree
directly) with options from the bch_extent_rebalance_entry, updating the
extent if necessary.

Since bch_extent_rebalance tracks where its option came from we can
preserve "inode options override filesystem options", even for indirect
extents where we don't have access to the inode the options came from.

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

bcachefs: bch2_write_inode() now checks for changing rebalance options

Previously, BCHFS_IOC_REINHERIT_ATTRS didn't trigger rebalance scans
when changing rebalance options - it had been missed, only the xattr
interface triggered them.

Ideally they'd be done by the transactional trigger, but unpacking the
inode to get the options is too heavy to be done in the low level
trigger - the inode trigger is run on every extent update, since the
bch_inode.bi_journal_seq has to be updated for fsync.

bch2_write_inode() is a good compromise, it already unpacks and repacks
and is not run in any super-fast paths.

Additionally, creating the new rebalance entry to trigger the scan is
now done in the same transaction as the inode update that changed the
options.

bcachefs: New bch_extent_rebalance fields

bcachefs: Add bch_io_opts fields for indicating whether the opts came from the inode

This is going to be used in the bch_extent_rebalance improvements, which
propagate io_path options into the extent (important for rebalance,
which needs something present in the extent for transactionally tagging
them in the rebalance_work btree, and also for indirect extents).

By tracking in bch_extent_rebalance whether the option came from the
filesystem or the inode we can correctly handle options being changed on
indirect extents.

bpf: Avoid deadlock caused by nested kprobe and fentry bpf programs

BPF program types like kprobe and fentry can cause deadlocks in certain
situations. If a function takes a lock and one of these bpf programs is
hooked to some point in the function's critical section, and if the
bpf program tries to call the same function and take the same lock it will
lead to deadlock. These situations have been reported in the following
bug reports.

Prevent kprobe and fentry bpf programs from attaching to these critical
sections by removing CC_FLAGS_FTRACE for percpu_freelist.o,
bpf_lru_list.o, queue_stack_maps.o, lpm_trie.o, ringbuf.o files.

The bugs reported by syzbot are due to tracepoint bpf programs being
called in the critical sections. This patch does not aim to fix deadlocks
caused by tracepoint programs. However, it does prevent deadlocks from
occurring in similar situations due to kprobe and fentry programs.
