The following sequence is problematic:
mtdblock_flush()
-->write_cached_data()
--->erase_write()
mtdblock: erase of region [0x40000, 0x20000] on "xxx" failed
Problem is: mtdblock_flush() always returns 0. Indeed, even if
write_cached_data() fails and data is not written to the device,
syscall_write() still returns success. Avoid this situation by
actually returning the error coming out of write_cached_data().

The current codebase makes use of the zero-length array language
extension to the C90 standard, but the preferred mechanism to declare
variable-length types such as these ones is a flexible array member[1][2],
introduced in C99:
struct foo {
int stuff;
struct boo array[];
};
By making use of the mechanism above, we will get a compiler warning
in case the flexible array does not occur last in the structure, which
will help us prevent some kind of undefined behavior bugs from being
inadvertently introduced[3] to the codebase from now on.
Also, notice that, dynamic memory allocations won't be affected by
this change:
"Flexible array members have incomplete type, and so the sizeof operator
may not be applied. As a quirk of the original implementation of
zero-length arrays, sizeof evaluates to zero."[1]
This issue was found with the help of Coccinelle.

The variable 'name' is released multiple times in the error path,
which may cause double free issues.
This problem is avoided by adding a goto label to release the memory
uniformly. And this change also makes the code a bit more cleaner.

The suffix was changed from "G" to "J" to classify between 1st generation
and 2nd generation serial NAND devices (which now belong to the Kioxia
brand).
As reference that's
1st generation device of 1Gbit product is "TC58CVG0S3HRAIG"
2nd generation device of 1Gbit product is "TC58CVG0S3HRAIJ".
The 8Gbit type "TH58CxG3S0HRAIJ" is new to Kioxia's serial NAND lineup and
the prefix was changed from "TC58" to "TH58".
Thus the functions were renamed from tc58cxgxsx_*() to tx58cxgxsxraix_*().

For non-fatal syndromes like LOCAL_LENGTH_ERR, recovery shouldn't be
triggered. In these scenarios, the RQ is not actually in ERR state.
This misleads the recovery flow which assumes that the RQ is really in
error state and no more completions arrive, causing crashes on bad page
state.

In striding RQ mode, the buffers of an RX WQE are first
prepared and posted to the HW using a UMR WQEs via the ICOSQ.
We maintain the state of these in-progress WQEs in the RQ
SW struct.
In the flow of ICOSQ recovery, the corresponding RQ is not
in error state, hence:
- The buffers of the in-progress WQEs must be released
and the RQ metadata should reflect it.
- Existing RX WQEs in the RQ should not be affected.
For this, wrap the dealloc of the in-progress WQEs in
a function, and use it in the ICOSQ recovery flow
instead of mlx5e_free_rx_descs().

When resetting the RQ (moving RQ state from RST to RDY), the driver

In striding RQ mode, we maintain a field that reflects the actual

It was mistakenly not reset together with the WQ. Fix this here.

Add number of WQEBBs (WQE's Basic Block) to WQE info struct. Set the
number of WQEBBs on WQE post, and increment the consumer counter (cc)
on completion.
In case of error completions, the cc was mistakenly not incremented,
keeping a gap between cc and pc (producer counter). This failed the

There are few maximum bus frequencies being used in the I²C core code.
Provide generic definitions for bus frequencies and use them in the core.
The drivers may use predefined constants where it is appropriate.
Some of them are already using these under slightly different names.
We will convert them later to use newly introduced defines.
Note, the name of modes are chosen to follow well established naming
scheme [1].
These definitions will also help to avoid typos in the numbers that
may lead to subtle errors.

Using huge page-table entries requires that the physical address of the
start of a buffer object is huge page size aligned.
Make a special version of the TTM range manager that accomplishes this,
but falls back to a smaller page size alignment (PUD->PMD, PMD->NORMAL)
to avoid eviction.
If other drivers want to use it in the future, it can be made a
TTM generic helper. Note that drivers can force eviction for a certain
alignment by assigning the TTM GPU alignment correspondingly.

Support huge (PMD-size and PUD-size) page-table entries by providing a
huge_fault() callback.
We still support private mappings and write-notify by splitting the huge
page-table entries on write-access.
Note that for huge page-faults to occur, either the kernel needs to be
compiled with trans-huge-pages always enabled, or the kernel needs to be
compiled with trans-huge-pages enabled using madvise, and the user-space
app needs to call madvise() to enable trans-huge pages on a per-mapping
basis.
Furthermore huge page-faults will not succeed unless buffer objects and
user-space addresses are aligned on huge page size boundaries.

When we discard something that is present in the journal, we flush the
journal first, so that discarded blocks are not overwritten by the journal
content.

Add an argument "allow_discards" that enables discard processing on
dm-integrity device. Discards are only allowed to devices using
internal hash.
When a block is discarded the integrity tag is filled with
DISCARD_FILLER (0xf6) bytes.

get_mode() is used to retrieve the active mode state. Settings-A
config is used during active state, whilst Settings-B is for
suspend. This means we only need to check the sleep field of each
buck and LDO as that field solely relates to Settings-A config.
This change is a clone of the get_mode() update which was committed
as part of:
- regulator: da9062: fix suspend_enable/disable preparation

Following commits will make it possible to shrink or extend the device. If
the device was shrunk, we don't want to replay journal data pointing past
the end of the device.

Since the commit 72deb455b5ec619ff043c30bc90025aa3de3cdda ("block:
remove CONFIG_LBDAF") sector_t is always defined as unsigned long
long.
Delete the needless type casts in printk and avoids some warnings if
DEBUG_PRINT is defined.
