2017-08-28android: binder: Add shrinker tracepointsSherry Yang
Add tracepoints in binder transaction allocator to record lru hits and alloc/free page. Signed-off-by: Sherry Yang <sherryy@android.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
2017-07-17binder: refactor binder ref inc/dec for thread safetyTodd Kjos
Once locks are added, binder_ref's will only be accessed safely with the proc lock held. Refactor the inc/dec paths to make them atomic with the binder_get_ref* paths and node inc/dec. For example, instead of: ref = binder_get_ref(proc, handle, strong); ... binder_dec_ref(ref, strong); we now have: ret = binder_dec_ref_for_handle(proc, handle, strong, &rdata); Since the actual ref is no longer exposed to callers, a new struct binder_ref_data is introduced which can be used to return a copy of ref state.

2017-07-17binder: separate out binder_alloc functionsTodd Kjos
Continuation of splitting the binder allocator from the binder driver. Separate binder_alloc functions from normal binder functions. Protect the allocator with a separate mutex. Signed-off-by: Todd Kjos <tkjos@google.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
2017-07-17binder: separate binder allocator structure from binder procTodd Kjos
The binder allocator is logically separate from the rest of the binder drivers. Separating the data structures to prepare for splitting into separate file with separate locking. Signed-off-by: Todd Kjos <tkjos@google.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
2014-10-20staging: android: binder: move to the "real" part of the kernelGreg Kroah-Hartman
The Android binder code has been "stable" for many years now. No matter what comes in the future, we are going to have to support this API, so might as well move it to the "real" part of the kernel as there's no real work that needs to be done to the existing code.
