This adds i_seqcnt to inode structure and then uses i_size_read() and
i_size_write() to provide atomic access to i_size. This is port
of Andrea Arcangeli i_size atomic access patch from 2.4. This only
uses the generic reader/writer consistent mechanism.
re-diff against 2.5.70.
This patch has been tested on 1 proc, 2 proc, and 8 proc machines.
