From 2be9737cf449dd0650c85ee5168d09b12d386077 Mon Sep 17 00:00:00 2001 From: Tao Bao Date: Mon, 15 Apr 2019 12:45:50 -0700 Subject: Remove the FD parameter from FuseDataProvider ctor. This leaves the FD implementation details to subclasses. In particular, it allows minadbd to do additional works with the FD after sideloading. Bug: 128415917 Test: atest recovery_component_test Test: atest minadbd_test Test: Sideload package on taimen.
