From 310e31989ec5e02a1706c1f918575a6b9ac24bc4 Mon Sep 17 00:00:00 2001 From: Nika Layzell Date: Tue, 3 May 2022 23:30:32 +0000 Subject: [PATCH] Bug 1754004 - Part 2: Remove the PFileDescriptorSet interface, r=asuth,necko-reviewers,kershaw This interface should no longer be required due to the changes in part 1 limiting the complexity of IPCStream instances and limiting the number of file descriptors which a single stream can attach to a message. Removing this interface is necessary to serialize nsIInputStream instances over arbitrary toplevel protocols and non-protocol IPC in the future.
