The person who had the problem is actually using the Debian tree which carried over a patch from 2.4 that removed the truncate_inode_pages call in set_blocksize. So I appologise for the noise.
However, may I ask what is preventing us from achieving the goal that the page cache backed buffer heads can be resized without throwing away the pages?
In particular, aside from the buffer_error() call, is there any problems with not throwing the pages away upon a resize?
