migrate_task_rq_fair resets the scan rate for NUMA balancing on every

saturation, this may result in the scan rate being pegged at maximum and

Currently task scan rate is reset when numa balancer migrates the task

Since we switched to using SRCU for tracepoints used in the idle path,
we can no longer use rcu_dereference_sched for dereferencing points in
trace-event hooks.
Since tracepoints can now use either SRCU or sched-RCU, just use
rcu_dereference_raw for traceevents just like we're doing when

I have used the pstore tree from next-20180802 for today.

I take that one back, ksys_mount() does check for error properly so just

The way I read Greg's comment was that he agreed to the proposed changes
and is waiting for a new version.
I'm writing a longer reply than I should because I don't like people
saying strncmp is safe just be

Hi Greg and Dominique,
We'd better reach an agreement about the patch fix. In my opinion,
replacing strlen(chan->tag) with a local variable sounds reasonable, and
changing strncmp to strcmp may be little beneficial, as strcmp is more
dangerours such as buffer-flow. So I'd like to hear your suggest
when firmware is in filesystem, request_firmware will load it,
and copy it to vmalloc memory, that is page align memory.
but when firmware is builtin, it is 8 bytes or 4 bytes alignment.
make sure builtin firmware is page algnment, that can simplify algorithm
to handle firmware.
