MSM8926, while being 'just' an LTE-capable variant of MSM8226, the dts
needs to slightly change since the modem doesn't use the ext-bhs-reg and
needs mss-supply, therefore it gets a new compatible.
Since we already have two -common.dtsi files which are used on both
APQ8026/MSM8226 and MSM8926 devices, change the setup a bit by removing
the SoC include from those and requiring the device dts to pick the
correct one.

USB phys in ipq9574 use the 'L5' regulator. The commit ec4f047679
("arm64: dts: qcom: ipq9574: Enable USB") incorrectly specified it as
'L2'. Because of this when the phy module turns off/on its regulators,
the wrong regulator is turned off/on resulting in 2 issues, namely the
correct regulator related to the USB phy is not turned off/on and the
module powered by the incorrect regulator is affected.

We're improving our handling of write errors - we shouldn't write
degraded data just because a write failed once, we should retry it (on
other devices, if possible).
But for this to work, we need to kick devices out when they're only
returning errors - otherwise those retries will loop infinitely.
This adds a configurable timeout - if writes are failing for too long,
we'll set that device read-only.
In the future we should also implement more tracking and another knob
for an "allowed error rate", so that we can kick out drives that are
acting "unhealthy".
Another thing we'll want is a mechanism (likely in userspace) for
bringing a device back in after a transient error - perhaps a cable was
jiggled, or there was a controller reset.
After transient errors we also need a mechanism to walk (from the
journal) recent btree updates that weren't flushed to that device and
treat them as "degraded", since unflushed data may well not have been
written. Out of scope for this patch, but becoming relevant.
Signed-off-by: Kent Overstreet <kent.overstreet@linux.dev>
Previously, we woudn't try to read at all from a failed device - that
doesn't make much sense, the device may be unhealthy (perhaps taking
longer than it should to service reads), but if it's our only option we
should still try to read from it.
Now, bch2_bkey_pick_read_device() will pick failed devices only if there
are no non-failed replicas to read from.

This was completely fubar; it's now simplified a bit as well.
Note that for_each_online_member() takes and releases io_refs as it

We can't use the standard fs_holder_ops because they're meant for single
device filesystems - fs_bdev_mark_dead() in particular - and they assume
that the blk_holder is the super_block, which also doesn't work for a
multi device filesystem.
These generally follow the standard fs_holder_ops; the
locking/refcounting is a bit simplified because c->ro_ref suffices, and
bch2_fs_bdev_mark_dead() is not necessarily shutting down the entire
filesystem.
Signed-off-by: Kent Overstreet <kent.overstreet@linux.dev>
This is necessary for the new blk_holder_ops, which want the vfs
super_block available for synchronization.
Signed-off-by: Kent Overstreet <kent.overstreet@linux.dev>
Note that we open block devices before we allocate bch_fs, but once
attached to a filesystem they will be closed before the bch_fs is torn
down - so stashing a pointer without a refcount looks incorrect but it's
not.

This implements a new extent field bitflags that apply to the whole
extent. There's been a couple things we've wanted this for in the past,
but the immediate need is extent poisoning, to solve a rebalance issue.
Unknown extent fields can't be parsed (we won't known their size, so we
can't advance to the next field), so this is an incompat feature, and
using it prevents the filesystem from being mounted by old versions.
This also adds the BCH_EXTENT_poisoned flag; this indicates that the
data is known to be bad (i.e. there was a checksum error, and we had to
write a new checksum) and reads will return errors.
