bcachefs: bch2_dir_emit() - fix directory reads in the fuse driver
Commit 0c0cbfdb84725e9933a24ecf47c61bdeeda06ba2 dropped the ctx->pos
update before the call to dir_emit. This breaks the userspace
implementation, causing the directory reads to be stuck in an infinite
loop. This doesn't happen in the kernel because the vfs handles the
updates to ctx->pos, but in the fuse implementation nobody updates
it.

bcachefs: Eytzinger accumulation for accounting keys
The btree write buffer takes as input keys from the journal, sorts them,
deduplicates them, and flushes them back to the btree in sorted order.
The disk space accounting rewrite is moving accounting to normal btree
keys, with update (in this case deltas) accumulated in the write buffer
and then flushed to the btree; but this is going to increase the number
of keys handled by the write buffer by perhaps as much as a factor of
3x-5x.
The overhead from copying around and sorting this many keys would cause
a significant performance regression, but: there is huge locality in
updates to accounting keys that we can take advantage of.
Instead of appending accounting keys to the list of keys to be sorted,
this patch adds an eytzinger search tree of recently seen accounting
keys. We look up the accounting key in the eytzinger search tree and
apply the delta directly, adding it if it doesn't exist, and
periodically prune the eytzinger tree of unused entries.

bcachefs: Disk space accounting rewrite
Main part of the disk accounting rewrite.
This is a wholesale rewrite of the existing disk space accounting, which
relies on percepu counters that are sharded by journal buffer, and
rolled up and added to each journal write.
With the new scheme, every set of counters is a distinct key in the
accounting btree; this fixes scaling limitations of the old scheme,
where counters took up space in each journal entry and required multiple
percpu counters.
Now, in memory accounting requires a single set of percpu counters - not
multiple for each in flight journal buffer - and in the future we'll
probably also have counters that don't use in memory percpu counters,
they're not strictly required.
An accounting update is now a normal btree update, using the btree write
buffer path. At transaction commit time, we apply accounting updates to
the in memory counters, which are percpu counters indexed in an
eytzinger tree by the accounting key.

Until accounting keys hit the btree, they are deltas, not new versions
of the existing key; this means we have to teach journal replay to
accumulate them.
Additionally, the journal doesn't track precisely which entries have
been flushed to the btree; it only tracks a range of entries that may
possibly still need to be flushed.
That means we need to compare accounting keys against the version in the
btree and only flush updates that are newer.
There's another wrinkle with the write buffer: if the write buffer
starts flushing accounting keys before journal replay has finished
flushing accounting keys, journal replay will see the version number
from the new updates and updates from the journal will be lost.
To avoid this, journal replay has to flush accounting keys first, and
we'll be adding a flag so that write buffer flush knows to hold

Mount options that take the name of a device that may be part of a

This change adds a printbuf parameter to bch2_parse_mount_opts() which

This functionality is not currently needed, but will be used after

because using the new mount API, we will process mount options prior to
opening the FS, but the new API doesn't provide a convenient way to
"replay" mount option parsing. So we save these options ourselves to
accomplish this.
This change also splits out the code to parse a single option into

When a software KASAN mode is enabled, the fortify tests emit warnings

[ more and more similar warnings... ]
Commit 9c2d1328f88a ("kbuild: provide reasonable defaults for tool
coverage") removed KASAN flags from non-kernel objects by default.
It was an intended behavior because lib/test_fortify/*.c are unit
tests that are not linked to the kernel.
As it turns out, some architectures require -fsanitize=kernel-(hw)address
to define __SANITIZE_ADDRESS__ for the fortify tests.
Without __SANITIZE_ADDRESS__ defined, arch/arm/include/asm/string.h
defines __NO_FORTIFY, thus excluding <linux/fortify-string.h>.
This issue does not occur on x86 thanks to commit 4ec4190be4cf
("kasan, x86: don't rename memintrinsics in uninstrumented files"),
but there are still some architectures that define __NO_FORTIFY
in such a situation.
Set KASAN_SANITIZE=y explicitly to the fortify tests.

After 8d1001f7bdd0 (kbuild: rpm-pkg: fix build error with CONFIG_MODULES=n),
the following warning "warning: File listed twice: *.dtb" is appearing for

The reason is that the commented commit already adds the folder

/lib/modules/%{KERNELRELEASE}/dtb is no longer necessary, just remove it.
because the trailing comma is included in the patch level part of the

breakage (as it impacts the configuration stage and it is present in all
LTS branches), it would be good to make ld-version.sh more robust
against such miniscule changes like this one.

after just numbers and periods, replacing of the current removal of
everything after a hyphen. ld-version.sh continues to work for a number
of distributions (Arch Linux, Debian, and Fedora) and the kernel.org

There are many generations of omaps to maintain, and I will be only active
as a hobbyist with time permitting. Let's add more maintainers to ensure
continued Linux support.
TI is interested in maintaining the active SoCs such as am3, am4 and
dra7. And the hobbyists are interested in maintaining some of the older
devices, mainly based on omap3 and 4 SoCs.
Kevin and Roger have agreed to maintain the active TI parts. Both Kevin
and Roger have been working on the omap variants for a long time, and
have a good understanding of the hardware.
Aaro and Andreas have agreed to maintain the community devices. Both Aaro
and Andreas have long experience on working with the earlier TI SoCs.

drop the link to my old omap web page.

i40e: fix: remove needless retries of NVM update
Remove wrong EIO to EGAIN conversion and pass all errors as is.
After commit 230f3d53a547 ("i40e: remove i40e_status"), which should only
replace F/W specific error codes with Linux kernel generic, all EIO errors
suddenly started to be converted into EAGAIN which leads nvmupdate to retry
until it timeouts and sometimes fails after more than 20 minutes in the
middle of NVM update, so NVM becomes corrupted.
The bug affects users only at the time when they try to update NVM, and
only F/W versions that generate errors while nvmupdate. For example, X710DA2
with 0x8000ECB7 F/W is affected, but there are probably more...
Command for reproduction is just NVM update:
./nvmupdate64
The problematic code did silently convert EIO into EAGAIN which forced
nvmupdate to ignore EAGAIN error and retry the same operation until timeout.
That's why NVM update takes 20+ minutes to finish with the fail in the end.

When user submits a rxfh set command without touching XFRM_SYM_XOR,
rxfh.input_xfrm is set to RXH_XFRM_NO_CHANGE, which is equal to 0xff.
Testing if (rxfh.input_xfrm & RXH_XFRM_SYM_XOR &&
!ops->cap_rss_sym_xor_supported)
return -EOPNOTSUPP;
Will always be true on devices that don't set cap_rss_sym_xor_supported,
since rxfh.input_xfrm & RXH_XFRM_SYM_XOR is always true, if input_xfrm
was not set, i.e RXH_XFRM_NO_CHANGE=0xff, which will result in failure
of any command that doesn't require any change of XFRM, e.g RSS context
or hash function changes.
To avoid this breakage, test if rxfh.input_xfrm != RXH_XFRM_NO_CHANGE
before testing other conditions. Note that the problem will only trigger
with XFRM-aware userspace, old ethtool CLI would continue to work.
