The handle_exit_race() function is defined in commit c158b461306df82
("futex: Cure exit race"), which never returns -EBUSY. This results
in a small piece of dead code in the attach_to_pi_owner() function:
int ret = handle_exit_race(uaddr, uval, p); /* Never return

If F2FS_FS is modular, enabling the compressions options
F2FS_FS_{LZ4,LZ4HZ,LZO,LZORLE,ZSTD} will make the (de)compression
algorithms {LZ4,LZ4HC,LZO,ZSTD}_{,DE}COMPRESS builtin instead of
modular, as the former depend on an intermediate boolean
F2FS_FS_COMPRESSION, which in-turn depends on tristate

I will try to find out why the target platform can't properly resume with

In some ACPI tables we encounter, devices use the _DEP method to assert
a dependence on other ACPI devices as opposed to the OpRegions that the
specification intends. We need to be able to find those devices "from"
the dependee, so add a callback and a wrapper to walk over the
acpi_dep_list and ret
The acpi_walk_dep_device_list() is not as generalisable as its name
implies, serving only to decrement the dependency count for each
dependent device of the input. Extend the function to instead accept
a callback which can be applied to all the dependencies in acpi_dep_list.
Replace all existing ca
ACPI devices with _HID INT3472 are currently matched to the tps68470
driver, however this does not cover all situations in which that _HID
occurs. We've encountered three possibilities:
1. On Chrome OS devices, an ACPI device with _HID INT3472 (representing
a physical TPS68470 device) that require
I need to be able to translate GPIO resources in an ACPI device's _CRS
into GPIO descriptor array. Those are represented in _CRS as a pathname
to a GPIO device plus the pin's index number: this function is perfect
for that purpose.
As it's currently only used internally within the GPIO layer, prov
Some places in the kernel allow users to map resources to a device
using device name (for example, in the struct gpiod_lookup_table).
Currently this involves waiting for the I2C client to have been registered
so we can use dev_name(&client->dev). We want to add a function to allow
users to refer to
This driver only covered one scenario in which ACPI devices with _HID
INT3472 are found, and its functionality has been taken over by the
intel-skl-int3472 module, so remove it.

Exactly. But for hugetlbfs/shmem ("!RAM-backed files") this is not what we

OK, then I must have misread your requirements. Maybe I just got lost in
all the combinations you have listed.
Another special case could be dax/pmem I think. You might want to fault
