ext4: only call ext4_truncate when size <= isize
commit 3da40c7b089810ac9cf2bb1e59633f619f3a7312 upstream.
At LSF we decided that if we truncate up from isize we shouldn't trim
fallocated blocks that were fallocated with KEEP_SIZE and are past the
new i_size. This patch fixes ext4 to do this.
[ Completely reworked patch so that i_disksize would actually get set
when truncating up. Also reworked the code for handling truncate so
that it's easier to handle. -- tytso ]
