Don't we also need to handle the new return value in a few other places
like cachefiles_read_reissue swap_readpage? Maybe those don't get
called on the currently converted instances, but just leaving them
without handling AOP_UPDATED_PAGE seems like a time bomb.
Looks good,

When there are back to back commits with async cursor update,
there is a case where second commit can program the DPU hw

This is an algorithm optimization. The reset operation when
setting the public key is repeated and redundant, so remove it.
At the same time, `sm2_ecc_os2ec()` is optimized to make the
function more simpler and more in line with the Linux code style.

Add a fault injection capability to call_int_hook macro. This will
facilitate testing of fault tolerance of the code that invokes
security hooks as well as the fault tolerance of the LSM

All templates and generic algorithms have been registered in
subsys_initcall instead of module_init. The ecrdsa algorithm
happened to be missed. Here is a fix for it.

Hello Paul,
The meaning behind 0x6100c can be found rather easily.
From drivers/scsi/smartpqi/smartpqi.h comes the main part
#define PQI_DATA_IN_OUT_PCIE_COMPLETION_TIMEOUT 0x61
the rest looks like additional status bytes reported whilst the error is
processed.
My conclusion is that some

LTR (Long Term Reference) frames are the frames that are encoded
sometime in the past and stored in the DPB buffer list to be used
as reference to encode future frames.

On CPU unplug tasks which are in a migrate disabled region cannot be pushed
to a different CPU until they returned to migrateable state.
Account the number of tasks on a runqueue which are in a migrate disabled
section and make the hotplug wait mechanism respect that.
Sign
Concurrent migrate_disable() and set_cpus_allowed_ptr() has
interesting features. We rely on set_cpus_allowed_ptr() to not return
until the task runs inside the provided mask. This expectation is
exported to userspace.
This means that any set_cpus_allowed_ptr() caller must wait until
migrate_enabl
Since we now migrate tasks away before DYING, we should also move
bandwidth unthrottle, otherwise we can gain tasks from unthrottle
after we expect all tasks to be gone already.
Also; it looks like the RT balancers don't respect cpu_active() and
instead rely on rq->online in part, complete this. T
The intent of balance_callback() has always been to delay executing
balancing operations until the end of the current rq->lock section.
This is because balance operations must often drop rq->lock, and that
isn't safe in general.
However, as noted by Scott, there were a few holes in that scheme;
