The quilt patch titled Subject: init: move cifs_root_data() prototype into linux/mount.h has been removed from the -mm tree. Its filename was init-move-cifs_root_data-prototype-into-linux-mounth.patch This patch was dropped because it was merged into the mm-nonmm-stable branch of git://git.kernel.org/pub/scm/linux/kernel/git/akpm/mm ------------------------------------------------------ From: Arnd Bergmann <arnd@xxxxxxxx> Subject: init: move cifs_root_data() prototype into linux/mount.h Date: Wed, 17 May 2023 15:11:00 +0200 cifs_root_data() is defined in cifs and called from early init code, but lacks a global prototype: fs/cifs/cifsroot.c:83:12: error: no previous prototype for 'cifs_root_data' Move the declaration from do_mounts.c into an appropriate header.
