  make set_blocksize() fail unless block device is opened exclusive (2024-05-02 17:39:44 -0400)

----------------------------------------------------------------
getting rid of bogus set_blocksize() uses, switching it
to struct file * and verifying that caller has device
opened exclusively.

----------------------------------------------------------------
Al Viro (9):
      bcache_register(): don't bother with set_blocksize()
      pktcdvd: sort set_blocksize() calls out
      swapon(2)/swapoff(2): don't bother with block size
      swapon(2): open swap with O_EXCL
      zram: don't bother with reopening - just use O_EXCL for open
      swsusp: don't bother with setting block size
      btrfs_get_bdev_and_sb(): call set_blocksize() only for exclusive opens
      set_blocksize(): switch to passing struct file *
      make set_blocksize() fail unless block device is opened exclusive
