Subject: [PATCH 0/5] v2 mm subsystem refcounter conversions
Date: Tue, 27 Jun 2017 14:48:42 +0300 [thread overview]
Message-ID: <1498564127-11097-1-git-send-email-elena.reshetova@intel.com> (raw)
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
