From b5d071c26697813bcceae320ba88dee2a2a73e51 Mon Sep 17 00:00:00 2001 From: Qi Wang Date: Wed, 8 Nov 2017 13:59:21 -0800 Subject: Fix unbounded increase in stash_decayed. Added an upper bound on how many pages we can decay during the current run. Without this, decay could have unbounded increase in stashed, since other threads could add new pages into the extents. --- include/jemalloc/internal/extent_externs.h | 3 ++- 1 file changed, 2 insertions(+), 1 deletion(-) (limited to 'include') diff --git a/include/jemalloc/internal/extent_externs.h b/include/jemalloc/internal/extent_externs.h index 9da5d010..132d8903 100644 --- a/include/jemalloc/internal/extent_externs.h +++ b/include/jemalloc/internal/extent_externs.h @@ -36,7 +36,8 @@ extent_t *extents_alloc(tsdn_t *tsdn, arena_t *arena, void extents_dalloc(tsdn_t *tsdn, arena_t *arena, extent_hooks_t **r_extent_hooks, extents_t *extents, extent_t *extent); extent_t *extents_evict(tsdn_t *tsdn, arena_t *arena, - extent_hooks_t **r_extent_hooks, extents_t *extents, size_t npages_min); + extent_hooks_t **r_extent_hooks, extents_t *extents, size_t npages_min, + size_t npages_max); void extents_prefork(tsdn_t *tsdn, extents_t *extents); void extents_postfork_parent(tsdn_t *tsdn, extents_t *extents); void extents_postfork_child(tsdn_t *tsdn, extents_t *extents); -- cgit v1.2.3
