Toomas Soome 3949295f36 libstand/dosfs: cache FAT32 in 128 Kb blocks to save loader memory ... Current implementation of dosfs in libstand reads full File Allocation Table to the RAM in the initialization code. In the extreme case of FAT32 filesystem, this structure will take up to 256-1024 Mb of loader memory, depending on the cluster size. Proposed patch reduces libstands/dosfs memory requirements to 128 Kb for all variants of dosfs filesystem. For FAT12 and FAT16 filesystems, File Allocation Table is cached in full, as before. For FAT32, File Allocation Table is broken into the equal blocks of 128 Kilobytes (32768 entries), and only current block is cached. Because per-filesystem context is now small, global FAT cache (for all instances of dosfs filesystem) is replaced by local per-instance cache.
