generic: require filesize to be greater than fs block size in

Browse Source 
generic/240
Date: Wed, 11 Dec 2013 11:21:28 -0000
From: Stanislav Kholmanskikh <stanislav.kholmanskikh@oracle.com>

If we execute generic/240 on a fs which has its fs block size greater
than 64k (for example, NFS), this test will fail with:

  io_submit failed: Invalid argument

This will happen because in src/aio-dio-regress/aiodio_sparse2.c this
expression

  num_aio = filesize / step;

will set num_aio to 0 and this means that no io_prep_write() will happen
before calling io_submit().

Fixing filesize to be 8 * "fs block size".
