A low local/remote numa hinting fault ratio is potentially explained by
failed migrations. This patch adds a tracepoint that fires when migration
fails due to migration rate limitation.

move_task() is called from move_one_task and move_tasks and is an
approximation of load balancer activity. We should be able to track
tasks that move between CPUs frequently. If the tracepoint included node
information then we could distinguish between in-node and between-node
traffic for load bala
This patch adds three tracepoints
o trace_sched_move_numawhen a task is moved to a node
o trace_sched_swap_numawhen a task is swapped with another task

The tracepoints allow the NUMA scheduler activity to be moni

Base pages are unmapped and flushed from cache and TLB during normal page
migration and replaced with a migration entry that causes any parallel or
gup to block until migration completes. THP does not unmap pages due to
a lack of support for migration entries at a PMD level. This allows races

There are a few subtle races, between change_protection_range (used by
mprotect and change_prot_numa) on one side, and NUMA page migration and
compaction on the other side.
The basic race is that there is a time window between when the PTE gets
made non-present (PROT_NONE or N
On a protection change it is no longer clear if the page should be still
accessible. This patch clears the NUMA hinting fault bits on a protection
change.

If the PMD is flushed then a parallel fault in handle_mm_fault() will enter
the pmd_none and do_huge_pmd_anonymous_page() path where it'll attempt
to insert a huge zero page. This is wasteful so the patch avoids clearing
the PMD when setting pmd_numa.

The TLB must be flushed if the PTE is updated but change_pte_range is clearing
the PTE while marking PTEs pte_numa without necessarily flushing the TLB if it

We execute collapse range multiple times on same file.
Each collapse range call collapses a single alternate block.
After the test execution, file will be left with 80 blocks and
as much number of extents.
We also check for file system consistency after the completion.
