In order to protect against ptrace(2) and similar attacks on container
runtimes when they join namespaces, many runtimes set mm->dumpable to
SUID_DUMP_DISABLE. However, doing this means that attempting to set up
an unprivileged user namespace will fail because an unprivileged process
can no longer
This patch is to extends soft offlining framework to support
non-lru page, which already support migration after
commit bda807d44454 ("mm: migrate: support non-lru movable page
migration")
When memory corrected errors occur on a non-lru movable page,
we can choose to stop using it by migrating dat

Userspace applications should be allowed to expect the membarrier system
call with MEMBARRIER_CMD_SHARED command to issue memory barriers on
nohz_full CPUs, but synchronize_sched() does not take those into
account.
Given that we do not want unrelated processes to be able

These functions (rcu_exp_gp_seq_start(), rcu_exp_gp_seq_end(),
rcu_exp_gp_seq_snap(), and rcu_exp_gp_seq_done() seemed too obvious
to comment when written, but not so much when being documented.
This commit therefore adds header comments to each of them.

Expedited grace periods no longer fall back to normal grace periods
in response to lock contention, given that expedited grace periods
now use the rcu_node tree so as to avoid contention. This commit
therfore removes the expedited_normal counter.

Hi Jason,
I've been taking a look at your patch, and i think it's... problematic.
You're using a union for the entropy_u64 and entropy_u32 arrays, and
the position field is used to indexed into those two arrays.
So if the first caller calls get_random_u64 with position=0, it will
get the first 6

llist.h comments are confusing about when locking is needed versus when it
isn't. Clarify these comments by being more descriptive about why locking is
needed for llist_del_first.
