Why is bwrite not implemented in Linux?
What would be the implementation of bwrite if it can be done?
The following is the implementation of bread in fs/buffer.c
struct buffer_head * bread(kdev_t dev, int block, int size)
{
struct buffer_head * bh;
bh = getblk(dev, block, size);
touch_buffer(bh);
if (buffer_uptodate(bh)) {
conditional_schedule();
return bh;
}
ll_rw_block(READ, 1, &bh);
wait_on_buffer(bh);
if (buffer_uptodate(bh))
return bh;
brelse(bh);
return NULL;
}
