  "message": "fork/exec: cleanup mm initialization\n\nmm initialization on fork/exec is spread all over the place, which makes\nthe code look inconsistent.\n\nWe have mm_init(), which is supposed to init/nullify mm\u0027s internals, but\nit doesn\u0027t init all the fields it should:\n\n - on fork -\u003emmap,mm_rb,vmacache_seqnum,map_count,mm_cpumask,locked_vm\n   are zeroed in dup_mmap();\n\n - on fork -\u003epmd_huge_pte is zeroed in dup_mm(), immediately before\n   calling mm_init();\n\n - -\u003ecpu_vm_mask_var ptr is initialized by mm_init_cpumask(), which is\n   called before mm_init() on both fork and exec;\n\n - -\u003econtext is initialized by init_new_context(), which is called after\n   mm_init() on both fork and exec;\n\nLet\u0027s consolidate all the initializations in mm_init() to make the code\nlook cleaner.\n\nSigned-off-by: Vladimir Davydov \u003cvdavydov@parallels.com\u003e\nCc: Oleg Nesterov \u003coleg@redhat.com\u003e\nCc: David Rientjes \u003crientjes@google.com\u003e\nCc: Christoph Lameter \u003ccl@linux.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n",
