Commit Message

Donet Tom Nov. 26, 2024, 3:56 p.m. UTC 
Commit ee86814b0562 ("mm/migrate: move NUMA hinting fault folio
isolation + checks under PTL") removed the code that had used
the vma argument in migrate_misplaced_folio.

Since the vma argument was no longer used in migrate_misplaced_folio,
this patch removed it.

changes:
V2:
  Added mm:migrate prefix in subject line.
V1:
https://lore.kernel.org/all/20241125075731.176573-1-donettom@linux.ibm.com/
