chain_allocator Struct Reference

Data Fields
struct linked_page *	chain
unsigned int	used_space
gfp_t	gfp_mask
int	safe_needed

Detailed Description

struct chain_allocator is used for allocating small objects out of a linked list of pages called 'the chain'.

The chain grows each time when there is no room for a new object in the current page. The allocated objects cannot be freed individually. It is only possible to free them all at once, by freeing the entire chain.

NOTE: The chain allocator may be inefficient if the allocated objects are not much smaller than PAGE_SIZE.
