Subject[PATCH 0/5] v2 mm subsystem refcounter conversions
Date
Changes in v2:
No changes in patches apart from trivial rebases, but now by
default refcount_t = atomic_t and uses all atomic standard operations
unless CONFIG_REFCOUNT_FULL is enabled. This is a compromize for the
systems that are critical on performance and cannot accept even
slight delay on the refcounter operations.


Elena Reshetova (5):
mm: convert bdi_writeback_congested.refcnt from atomic_t to refcount_t
mm: convert anon_vma.refcount from atomic_t to refcount_t
mm: convert kmemleak_object.use_count from atomic_t to refcount_t
mm: convert mm_struct.mm_users from atomic_t to refcount_t
mm: convert mm_struct.mm_count from atomic_t to refcount_t
