Subject: [PATCH v2 0/5] android: binder: move allocator metadata and add shrinker
Date: Wed, 23 Aug 2017 08:46:38 -0700	[thread overview]
Message-ID: <20170823154643.2613-1-sherryy@android.com> (raw)

This patch set moves internal kernel data in the binder driver
out of mmap regions that is readable by user space. A shrinker
is added to the driver to dynamically manage the memory used
by binder transactions and only free pages when the system is
under memory pressure. This patch set also adds tests and
refactoring in binder allocator.

      android: binder: Refactor prev and next buffer into a helper function
      android: binder: Add allocator selftest
      android: binder: Move buffer out of area shared with user space
      android: binder: Add global lru shrinker to binder
      android: binder: Add shrinker tracepoints
