Type:unsigned int

Parameter:

Type	Parameter	Name
gfp_t	gfp_mask

4175

alloc_flags = The ALLOC_WMARK bits are used as an index to zone->watermark | check for correct cpuset

4178

BUILD_BUG_ON - break compile if a condition is true(__GFP_HIGH != (__force gfp_t)__GFP_HIGH set )

4186

alloc_flags |= (__force int)(gfp_mask & __GFP_HIGH)

4188

If gfp_mask & DOC: Watermark modifiers* Watermark modifiers -- controls access to emergency reserves* ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~* %__GFP_HIGH indicates that the caller is high-priority and that granting Then

4193

If Not (gfp_mask & __GFP_NOMEMALLOC) Then alloc_flags |= ry to alloc harder

4199

alloc_flags &= ~check for correct cpuset

4200

Else if Value for the false possibility is greater at compile time(rt_task(current process)) && Not in_interrupt() Then alloc_flags |= ry to alloc harder

4203

If gfp_mask & kswapd can wake Then alloc_flags |= allow waking of kswapd

4207

If gfpflags_to_migratetype(gfp_mask) == MIGRATE_MOVABLE Then alloc_flags |= allow allocations from CMA areas

4210

Return alloc_flags
