[PATCH v1 0/3] mm: mm_cid static initialization fixes

Posted by Mathieu Desnoyers 1 month, 2 weeks ago

Hi Andrew,

Here are 2 fixes for missing mm_cid fields for init_mm and efi_mm static
initialization. The renaming of cpu_bitmap to flexible_array (patch 2)
is needed for patch 3.

Those are relevant for mainline, with CC stable. They are based on
v6.19-rc2.

Mathieu Desnoyers (3):
  mm: Add missing static initializer for init_mm::mm_cid.lock
  mm: Rename cpu_bitmap field to flexible_array
  mm: Take into account mm_cid size for mm_struct static definitions
