Since the\nsuperseded transaction was never delivered, binder_apply_fd_fixups() was\nnever called and no fds were installed in the target process.\n\nWith is_failure=false, the BINDER_TYPE_FDA cleanup handler interprets\nstale buffer contents as installed fd numbers and passes them to\nbinder_deferred_fd_close(), closing unrelated file descriptors.\n\nPass is_failure=true since the transaction was never delivered to the\ntarget, matching the semantics of all other undelivered-transaction\ncleanup paths.","categories":["Operating
