Subject: [PATCH] tests: PAGE_SIZE larger than blocksize with hole

From: Andreas Dilger <andreas.dilger@...el.com>

Verify correct operation in the case of writing files with allocated
blocks at the end of the file beyond i_size.  This can happen for
PAGE_SIZE > blocksize, or through fallocate().

The f_eofblocks thest checks quite the same situation, but for broken
file system. This test is about correct file.
