syz-executor.5/13733 is trying to acquire lock:
 (&p->lock){+.+.+.}, at: [<ffffffff81507c66>] seq_read+0xd6/0x1240 fs/seq_file.c:178

but task is already holding lock:
 (sb_writers#4){.+.+.+}, at: [<ffffffff8149a6b6>] file_start_write include/linux/fs.h:2543 [inline]
 (sb_writers#4){.+.+.+}, at: [<ffffffff8149a6b6>] do_sendfile+0x8a6/0xba0 fs/read_write.c:1228

which lock already depends on the new lock.
