Alex Nixon 3971e1a917 VFS: increase pseudo-filesystem block size to PAGE_SIZE 
This commit:

    commit ba52de123d454b57369f291348266d86f4b35070
    Author: Theodore Ts'o <tytso@mit.edu>
    Date:   Wed Sep 27 01:50:49 2006 -0700

        [PATCH] inode-diet: Eliminate i_blksize from the inode structure

caused the block size used by pseudo-filesystems to decrease from
PAGE_SIZE to 1024 leading to a doubling of the number of context switches
during a kernbench run.
