liblog exposed __android_logger_get_buffer_size() which queries log size properties, but that should not be a generic library function. Logd should be the only process that queries these properties and other processes should query the actual used log sizes from logd via the android_logger_get_log_*_size() functions. Also, always use 1MB for log buffer tests, instead of just on host and various other clean up related to improper types. Test: log buffers are correctly sized Merged-In: I9b7c86bf58e569618737afe9097cf1c4d4e61d95 Change-Id: I9b7c86bf58e569618737afe9097cf1c4d4e61d95
