Name:xas_nomem() - Allocate memory if needed.*@xas: XArray operation state.*@gfp: Memory allocation flags.* If we need to add new nodes to the XArray, we try to allocate memory* with GFP_NOWAIT while holding the lock, which will usually succeed.
Proto:bool xas_nomem(struct xa_state *xas, gfp_t gfp)
Type:bool
Parameter:
Type | Parameter | Name |
---|---|---|
struct xa_state * | xas | |
gfp_t | gfp |
300 | Return false |
302 | If private: The rest of the data structure is not to be used directly. & XA_FLAGS_ACCOUNT Then gfp |= __GFP_ACCOUNT |
305 | If Not xa_alloc Then Return false |
308 | xa_node = XAS_RESTART |
309 | Return true |

xa_store_order | If anyone needs this, please move it to xarray.c. We have no current* users outside the test suite because all current multislot users want* to use the advanced API. |

add_to_swap_cache | add_to_swap_cache resembles add_to_page_cache_locked on swapper_space,* but sets SwapCache flag and private instead of mapping and index. |
