Theodore Ts'o b9f1b63992 ext4: call sync_blockdev() before invalidate_bdev() in put_super() 
commit 89d96a6f8e6491f24fc8f99fd6ae66820e85c6c1 upstream.

Normally all of the buffers will have been forced out to disk before
we call invalidate_bdev(), but there will be some cases, where a file
system operation was aborted due to an ext4_error(), where there may
still be some dirty buffers in the buffer cache for the device.  So
try to force them out to memory before calling invalidate_bdev().

This fixes a warning triggered by generic/081:

WARNING: CPU: 1 PID: 3473 at /usr/projects/linux/ext4/fs/block_dev.c:56 __blkdev_put+0xb5/0x16f()
