Extent purge hook.An extent purge function conforms to the
extent_purge_t
type and discards physical pages within the virtual memory mapping associated with an extent at givenaddr
andsize
atoffset
bytes, extending forlength
on behalf of arenaarena_ind
. A lazy extent purge function (e.g. implemented viamadvise(..., MADV_FREE)
) can delay purging indefinitely and leave the pages within the purged virtual memory range in an indeterminite state, whereas a forced extent purge function immediately purges, and the pages within the virtual memory range will be zero-filled the next time they are accessed. If the function returns true, this indicates failure to purge.
