From: Al Viro Date: Thu, 30 May 2019 19:59:57 +0000 (-0400) Subject: init_rootfs(): don't bother with init_ramfs_fs() X-Git-Tag: Ubuntu-5.13.0-19.19~8057^2~3 X-Git-Url: https://git.proxmox.com/?a=commitdiff_plain;h=14a253ce4210cd2ef133b392062477e9d656db4a;p=mirror_ubuntu-jammy-kernel.git init_rootfs(): don't bother with init_ramfs_fs() the only thing done by the latter is making ramfs visible to mount(2); we don't need it there - rootfs is separate and, in fact, made visible to mount(2) in the same init_rootfs().
