It's almost impossible to get READA to do anything. For example, in
current 2.5, if a READA attempt is actually aborted, end_buffer_io_sync
reports a "buffer I/O error". Every time. And nobody has reported this.

It _is_ possible to hit this in 2.5, because of ext2_preread_inode().

Probably, also it's possible to hit it in 2.4 with hundreds of processes
all issuing ext3 directory readahead. But it's pretty remote.
