fs: fix do_mount_root() false positive kmemcheck warning
This false positive is due to the fact that do_mount_root() fakes a mount option (which is normally read from userspace), and the kernel unconditionally reads a whole page for the mount option. Hide the false positive by using the new __getname_gfp() with the __GFP_NOTRACK_FALSE_POSITIVE flag. Cc: Al Viro <viro@zeniv.linux.org.uk> Signed-off-by: Vegard Nossum <vegard.nossum@gmail.com>
