Too large st_blocks values are now ignored (ticket #157). With XFS, using "allocsize=64m" mount option results in large preallocation being reported in the st_blocks as returned by fstat() till the file is closed. This in turn results in incorrect cache size calculations and wrong clearing based on max_size. To avoid too aggressive cache clearing on such volumes, st_blocks values which result in sizes larger than st_size and eight blocks (an arbitrary limit) are no longer trusted, and we use st_size instead. The ngx_de_fs_size() counterpart is intentionally not modified, as it is used on closed files and hence not affected by this problem.
