Revert "mm/filemap: avoid buffered read/write race to read inconsistent data"
This reverts commit e2c27b803bb6 ("mm/filemap: avoid buffered read/write
race to read inconsistent data"). After making the i_size_read/write
helpers be smp_load_acquire/store_release(), it is already guaranteed that
changes to page contents are visible before we see increased inode size,
so the extra smp_rmb() in filemap_read() can be removed.
