page_alloc_shuffle

Name:Depending on the architecture, module parameter parsing may run* before, or after the cache detection

Proto:__meminit void page_alloc_shuffle(enum mm_shuffle_ctl ctl)

Type:void

Parameter:

Type	Parameter	Name
enum mm_shuffle_ctl	ctl

24

If ctl == SHUFFLE_FORCE_DISABLE Then Atomically set a bit in memory

27

If st_bit - Determine whether a bit is set*@nr: bit number to test*@addr: Address to start counting from Then

28

If st_and_clear_bit - Clear a bit and return its old value*@nr: Bit to clear*@addr: Address to count from* This is an atomic fully-ordered operation (implied full memory barrier). Then static_branch_disable( & page_alloc_shuffle_key)

30

Else if ctl == SHUFFLE_ENABLE && Not st_and_set_bit - Set a bit and return its old value*@nr: Bit to set*@addr: Address to count from* This is an atomic fully-ordered operation (implied full memory barrier). Then Normal usage; boolean enable/disable.( & page_alloc_shuffle_key)
