Wait for an IO to complete

[Rishi Agrawal <rishi.b.agrawal@xxxxxxxxx>]

Hi All,

I want to wait in my code till the IO actually goes to the disk.

For example

struct buffer_head *bh=sb_bread(sb, 20)

strcpy(bh->b_data, "Some Data");

/* mark and sync */

mark_buffer_dirty(bh);

sync_dirty_buffer(bh);

The above code only adds the bh to the request queue and returns.

I need something

write_buffer_to_disk(bh)

Which will return only if the data has been written on disk.

Please help
