File linux-2.6-inode-diet-eliminate-i_blksize-and-use-a-per-superblock-default.patch of Package kernel

From: "Theodore Ts'o" <tytso@mit.edu>

This eliminates the i_blksize field from struct inode.  Filesystems that want
to provide a per-inode st_blksize can do so by providing their own getattr
routine instead of using the generic_fillattr() function.

Note that some filesystems were providing pretty much random (and incorrect)
values for i_blksize.
