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 <viro@zeniv.linux.org.uk> Cc: "David S.
