Or can this part be merged first (just some cleanups and preparations)? Or should I post the part 2 and part 3 first for everyone to review together? Either one is fine for me. :) Thanks, Qi > > Qi Zheng (5): > mm: move some shrinker-related function declarations to mm/internal.h > mm: vmscan: move shrinker-related code into a separate file > mm: shrinker: remove redundant shrinker_rwsem in debugfs operations > drm/ttm: introduce pool_shrink_rwsem > mm: shrinker: add a secondary array for shrinker_info::{map, > nr_deferred} > > drivers/gpu/drm/ttm/ttm_pool.c | 17 +- > include/linux/memcontrol.h | 12 +- > include/linux/shrinker.h | 37 +- > mm/Makefile | 4 +- > mm/internal.h | 28 ++ > mm/shrinker.c | 751 +++++++++++++++++++++++++++++++++ > mm/shrinker_debug.c | 18 +- > mm/vmscan.c | 701 ------------------------------ > 8 files changed, 818 insertions(+), 750 deletions(-) > create mode 100644 mm/shrinker.c >
Hi all, To make reviewing and updating easier, I've chosen to split the previous patchset[1] into the following three parts: part 1: some cleanups and preparations part 2: introduce new APIs and convert all shrinnkers to use these part 3: implement lockless slab shrink This series is the part 1 and is based on the next-20230815. Comments and suggestions are welcome.
