/* Figure out maximum filesize, on Linux this can depend on
* the filesystem blocksize (on 32 bit platforms).
* __block_write_begin does this in an [unsigned] long...
* page->index << (PAGE_CACHE_SHIFT - bbits)
* page->index << (PAGE_SHIFT - bbits)
* So, for page sized blocks (4K on 32 bit platforms),
* this wraps at around 8Tb (hence MAX_LFS_FILESIZE which is
* (((u64)PAGE_CACHE_SIZE << (BITS_PER_LONG-1))-1)
* (((u64)PAGE_SIZE << (BITS_PER_LONG-1))-1)
* but for smaller blocksizes it is less (bbits = log2 bsize).
* Note1: get_block_t takes a long (implicit cast from above)
* Note2: The Large Block Device (LBD and HAVE_SECTOR_T) patch
