VFS: increase pseudo-filesystem block size to PAGE_SIZE

This commit:
commit ba52de123d454b57369f291348266d86f4b35070
Author: Theodore Ts'o <tytso@mit.edu>

[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.
