The point of using set_child_tid to hold the kthread pointer was that
it already did what is necessary. There are now restrictions on when
set_child_tid can be initialized and when set_child_tid can be used in
schedule_tail. Which indicates that continuing to use set_child_tid
to hold the kthread pointer is a bad idea.
Instead of continuing to use the set_child_tid field of task_struct
generalize the pf_io_worker field of task_struct and use it to hold
the kthread pointer.
Rename pf_io_worker (which is a void * pointer) to worker_private so
it can be used to store kthreads struct kthread pointer. Update the
kthread code to store the kthread pointer in the worker_private field.
Remove the places where set_child_tid had to be dealt with carefully
because kthreads also used it.

In commit 8a5a75e5e9e5 ("of/fdt: Make sure no-map does not remove
already reserved regions") we returned -EBUSY when trying to mark
regions as no-map when they intersect with reserved memory. The goal was
to find bad no-map reserved memory DT nodes that would unmap the kernel
text/data sections.
The problem is the reserved memory check will still trigger if the DT
has a /memreserve/ that completely subsumes the no-map memory carveouts
in the reserved memory node _and_ that region is also not part of the
memory reg property. For example in sc7180.dtsi we have the following
reserved-memory and memory node:
memory@80000000 {
/* We expect the bootloader to fill in the size */
reg = <0 0x80000000 0 0>;
};
smem_mem: memory@80900000 {
reg = <0x0 0x80900000 0x0 0x200000>;
no-map;
};
and the memreserve filled in by the bootloader is
/memreserve/ 0x80800000 0x400000;
while the /memory node is transformed into
memory@80000000 {
/* The bootloader fills in the size, and adds another region */
reg = <0 0x80000000 0 0x00800000>,
<0 0x80c00000 0 0x7f200000>;
};
The smem region is doubly reserved via /memreserve/ and by not being
part of the /memory reg property. This leads to the following warning
printed at boot.
OF: fdt: Reserved memory: failed to reserve memory for node 'memory@80900000': base 0x0000000080900000, size 2 MiB
Otherwise nothing really goes wrong because the smem region is not going
to be mapped by the kernel's direct linear mapping given that it isn't
part of the memory node. Therefore, let's only consider this to be a
problem if we're trying to mark a region as no-map and it is actually
memory that we're intending to keep out of the kernel's direct mapping
but it's already been reserved.

The cells_name field of of_phandle_iterator might be NULL. Use the
phandle name instead. With this change instead of:
OF: /soc/pinctrl@1000000: (null) = 3 found 2
We get:
OF: /soc/pinctrl@1000000: phandle pinctrl@1000000 needs 3, found 2
Which is a more helpful messages making DT debugging easier.
In this particular example the phandle name looks like duplicate of the
same node name. But note that the first node is the parent node
(it->parent), while the second is the phandle target (it->node). They
happen to be the same in the case that triggered this improvement. See

The previous commit fixed up all shell scripts to not include
include/config/auto.conf.
Now that include/config/auto.conf is only included by Makefiles,
we can change it into a more Make-friendly form.
Previously, Kconfig output string values enclosed with double-quotes
(both in the .config and include/config/auto.conf):
CONFIG_X="foo bar"
Unlike shell, Make handles double-quotes (and single-quotes as well)
verbatim. We must rip them off when used.
There are some patterns:
[1] $(patsubst "%",%,$(CONFIG_X))
[2] $(CONFIG_X:"%"=%)
[3] $(subst ",,$(CONFIG_X))
[4] $(shell echo $(CONFIG_X))
These are not only ugly, but also fragile.
[1] and [2] do not work if the value contains spaces, like
CONFIG_X=" foo bar "
[3] does not work correctly if the value contains double-quotes like
CONFIG_X="foo\"bar"
[4] seems to work better, but has a cost of forking a process.
Anyway, quoted strings were always PITA for our Makefiles.
This commit changes Kconfig to stop quoting in include/config/auto.conf.
These are the string type symbols referenced in Makefiles or scripts:

Richard Weinberger pointed out the risk of sourcing the kernel config
from shell scripts [1], and proposed some patches [2], [3]. It is a good
point, but it took a long time because I was wondering how to fix this.
This commit goes with simple grep approach because there are only a few
scripts including the kernel configuration.
scripts/link_vmlinux.sh has references to a bunch of CONFIG options,
all of which are boolean. I added is_enabled() helper as
scripts/package/{mkdebian,builddeb} do.
scripts/gen_autoksyms.sh uses 'eval', stating "to expand the whitelist
path". I removed it since it is the issue we are trying to fix.
I was a bit worried about the cost of invoking the grep command over
again. I extracted the grep parts from it, and measured the cost. It
was approximately 0.03 sec, which I hope is acceptable.

The complex macro, config_filename, was introduced to do:
[1] drop double-quotes from the string value
[2] add $(srctree)/ prefix in case the file is not found in $(objtree)
[3] escape spaces and more
[1] will be more generally handled by Kconfig later.
As for [2], Kbuild uses VPATH to search for files in $(objtree),
$(srctree) in this order. GNU Make can natively handle it.
As for [3], converting $(space) to $(space_escape) back and forth looks
questionable to me. It is well-known that GNU Make cannot handle file
paths with spaces in the first place.
Instead of using the complex macro, use $< so it will be expanded to
the file path of the key.
Remove config_filename, finally.

'make clean' removes files listed in 'targets'. It is redundant to
specify both 'targets' and 'clean-files'.
Move 'targets' assignments out of the ifeq-conditionals so
scripts/Makefile.clean can see them.
One effective change is that certs/certs/signing_key.x509 is now

We currently store large folios as 2^N consecutive entries. While this
consumes rather more memory than necessary, it also turns out to be buggy.
A writeback operation which starts within a tail page of a dirty folio will
not write back the folio as the xarray's dirty bit is only set on the
head index. With multi-index entries, the dirty bit will be found no
matter where in the folio the operation starts.
This does end up simplifying the page cache slightly, although not as
much as I had hoped.

This struct was used to pass data from callee function to its caller.
Its usage can be avoided.
Removing it results in less code without any damage to code readability.
Also it allows to consolidate ring size calculation into a single
function (ena_calc_io_queue_size()).

The print that indicates that device reset has finished is
currently called from ena_restore_device().
Move it to ena_fw_reset_device() as it is the more natural
location for it.

The ena_com_indirect_table_fill_entry() function only returns -EINVAL
or 0, no need to check for -EOPNOTSUPP.

LLQ entry length is 128 bytes. Therefore the maximum header in
the entry is calculated by:
tx_max_header_size =
LLQ_ENTRY_SIZE - DESCRIPTORS_NUM_BEFORE_HEADER * 16 =
128 - 2 * 16 = 96
This patch updates the documentation so that it states the correct
max header length.

Use the capabilities field to query the device for ENI stats
support.
This replaces the previous method that tried to get the ENI stats
during ena_probe() and used the success or failure as an indication
for support by the device.
Remove eni_stats_supported field from struct ena_adapter. This field
was used for the previous method of queriying for ENI stats support.
Change the severity level of the print in case of
ena_com_get_eni_stats() failure from info to error.
With the previous method of querying form ENI stats support, failure
to get ENI stats was normal for devices that don't support it.
With the use of the capabilities field such a failure is unexpected,
as it is called only if the device reported that it supports ENI
stats.
