Hi, I'd like to report a regression. Currently, if you create GRE
interface on the latest stable or LTS kernel (5.4 branch) with
unspecified remote destination it's MTU will be adjusted for header size
twice. For example:
$ ip link add name test type gre local 127.0.0.32
$ ip link show test | grep
In gup_test both gup_flags and test_flags use the same flags field.
This is broken.
Farther, in the actual gup_test.c all the passed gup_flags are erased and
unconditionally replaced with FOLL_WRITE.
Which means that test_flags are ignored, and code like this always
performs pin dump test:
155
For non-DMA usage, we have an easy way to associate a timestamp with a
sample: iio_pollfunc_store_time stores a timestamp in the primary
trigger IRQ handler and stm32_adc_trigger_handler runs in the IRQ thread
to push out the buffer along with the timestamp.
For this to work, the driver needs to r
When pages are pinned they can be faulted in userland and migrated, and
they can be faulted right in kernel without migration.
In either case, the pinned pages must end-up being pinnable (not movable).
