The only thing the passed root is used for is:
1. get a reference to the fs_info and to
2. call trace_btrfs_transaction_commit.
We can achieve 1) by simply referring to the fs_info from passed trans
object. As far as 2) is concerned cleanup_transaction is called from
only one place and the 'root' argument passed is the one from the trans
handle. No functional changes.

btrfs_write_and_wait_transaction is essentially a wrapper of
btrfs_write_and_wait_marked_extents with the addition of calling
clear_btree_io_tree. Having the code split doesn't really bring any
benefit. Open code the later into the former and add proper
documentation header.

This function is only ever used in __btrfs_end_transaction and
btrfs_commit_transaction so there is no need to export it via header.
Let's move it closer to where it's used, make it static and remove it
from the header. No functional changes.

Current u64 return from btrfs_dev_replace_cancel() was probably done
to match the btrfs_ioctl_dev_replace_args::result. However as our
actual return value fits in int, and it further gets typecast to u64,
so just return int.

Currently the function uses a hardcoded value for the checksum size of
a sector. This is fine, given that we currently support only a single
algorithm, whose checksum is 4 bytes == sizeof(u32). Despite not
having other algorithms, btrfs' design supports using a different
algorithm whith different space requirements. To future-proof the code
query the size of the currently used algorithm from the in-memory copy
of the super block. No functional changes.

Commit 0e8c36a9fd81 ("Btrfs: fix lots of orphan inodes when the space
is not enough") changed the way transaction reservation is made in
btrfs_evict_node and as a result this function became unused. This has
been the status quo for 5 years in which time no one noticed, so I'd
say it's safe to assume it's unlikely it will ever be used again.
Historical note: there were more attempts to remove the function, the
reasoning was missing and only based on some static analysis tool
reports. Other reason for rejection was that there seemed to be
connection to BTRFS_RESERVE_FLUSH_LIMIT and that would need to be
removeed to. This was not correct so removing the function is all we can
do.

Presently, failing a primary super block write but succeeding in at
least one super block write in general will appear to users as if
nothing important went wrong. However, upon unmounting and re-mounting,
the file system will be in a rolled back state. This was discovered
with a BCC program that uses bpf_override_return() to fail super block
writes.
This patch outputs an error clarifying that the primary super block
write has failed, so users can expect potentially erroneous behaviour.
It also forces wait_dev_supers() to return an error to its caller if
the primary super block write fails.

According to Apple's Developer Notes, all of the early PowerBook models
have their RTC connected to VIA1. Use the VIA clock ops as appropriate.
This was tested on a PowerBook 170.
Don't use the VIA ops when not appropriate. Calling unimplemented clock
or PRAM getter or setter ops can now result in an error instead of
failing silently.

In certain cases interrupt enablement will be delayed relative to when
the InterruptEnable bits are written. One example of this is when
a GPIO's "debounce" logice is first enabled. After enabling debounce,
there is a 900 us "warm up" period during which InterruptEnable[0]
(bit 11) will read as 0 despite being written 1. During this time
InterruptSts will not be updated, nor will interrupts be delivered, even
if the GPIO's interrupt configuration has been written to the register.
To work around this delay, poll the InterruptEnable bits after setting
them to ensure interrupts have truly been enabled in hardware before
returning from the irq_enable handler.

Signed-off-by: Daniel Borkmann <daniel@iogearbox.net>

The BTF (BPF Type Format) verifier needs to reuse the current
BPF verifier log. Hence, it requires the following changes:
(1) Expose log_write() in verifier.c for other users.
Its name is renamed to bpf_verifier_vlog().
(2) The BTF verifier also needs to check
'log->level && log->ubuf && !bpf_verifier_log_full(log);'
independently outside of the current log_write(). It is
because the BTF verifier will do one-check before
making multiple calls to btf_verifier_vlog to log
the details of a type.
Hence, this check is also re-factored to a new function
bpf_verifier_log_needed(). Since it is re-factored,
we can check it before va_start() in the current
bpf_verifier_log_write() and verbose().

====================
net: broadcom: Adaptive interrupt coalescing
This patch series adds adaptive interrupt coalescing for the Gigabit Ethernet
drivers SYSTEMPORT and GENET.
This really helps lower the interrupt count and system load, as measured by
vmstat for a Gigabit TCP RX session:
SYSTEMPORT:
without:
1 0 0 192188 0 25472 0 0 0 0 122100 38870 1 42 57 0 0
[ ID] Interval Transfer Bandwidth
[ 4] 0.0-10.0 sec 1.03 GBytes 884 Mbits/sec
with:
1 0 0 192288 0 25468 0 0 0 0 58806 44401 0 100 0 0 0
[ 5] 0.0-10.0 sec 1.04 GBytes 888 Mbits/sec
GENET:
without:
1 0 0 1170404 0 25420 0 0 0 0 130785 63402 2 85 12 0 0
[ ID] Interval Transfer Bandwidth
[ 4] 0.0-10.0 sec 1.04 GBytes 888 Mbits/sec
with:
1 0 0 1170560 0 25420 0 0 0 0 50610 48477 0 100 0 0 0
[ 5] 0.0-10.0 sec 1.05 GBytes 899 Mbits/sec
Please look at the implementation and let me know if you see any problems, this
was largely inspired by bnxt_en.

Unlike the moder modern SYSTEMPORT hardware, we do not have a
configurable TDMA timeout, which limits us to implement adaptive RX
interrupt coalescing only. We have each of our RX rings implement a
bcmgenet_net_dim structure which holds an interrupt counter, number of
packets, bytes, and a container for a net_dim instance.

Implement support for adaptive RX and TX interrupt coalescing using
net_dim. We have each of our TX ring and our single RX ring implement a
bcm_sysport_net_dim structure which holds an interrupt counter, number
of packets, bytes, and a container for a net_dim instance.
