Lots of errors referring to sched->plug when CONFIG_BLOCK
is not set.

E.g.:
../kernel/sched/core.c: In function ‘io_schedule_prepare’:
../kernel/sched/core.c:8331:13: error: ‘struct task_struct’ has no member named ‘plug’
   if (current->plug)
              ^~
../kernel/sched/core.c:8332:25: error: ‘struct task_struct’ has no member named ‘plug’
    blk_flush_plug(current->plug, true);
                          ^~
../fs/fs-writeback.c: In function ‘writeback_sb_inodes’:
../fs/fs-writeback.c:1896:15: error: ‘struct task_struct’ has no member named ‘plug’
     if (current->plug)
                ^~
../fs/fs-writeback.c:1897:27: error: ‘struct task_struct’ has no member named ‘plug’
      blk_flush_plug(current->plug, false);
                            ^~
