From 6659061045cc93f609e100b128f30581e5f012e9 Mon Sep 17 00:00:00 2001 From: Kees Cook Date: Wed, 10 Jun 2020 08:20:05 -0700 Subject: fs: Move __scm_install_fd() to __receive_fd() In preparation for users of the "install a received file" logic outside of net/ (pidfd and seccomp), relocate and rename __scm_install_fd() from net/core/scm.c to __receive_fd() in fs/file.c, and provide a wrapper named receive_fd_user(), as future patches will change the interface to __receive_fd(). Additionally add a comment to fd_install() as a counterpoint to how __receive_fd() interacts with fput(). Cc: Alexander Viro Cc: "David S.
