2012-10-28Make ext2fs work with partitions bigger than 2Gb.Maksym Planeta
This commit is port of large store patch from debian repository. Additionally this patch was changed to use new libpager interface. The main idea behind this patch is to use special disk cache up to 2Gb size instead of mapping the whole partition. This cache is used to map only those pages of partitions that are used at the moment or were used recently. This allows to map only up to 2Gb of memory, although partition could be much bigger. This commit does not bring support for large files, only for partitions! * ext2fs/balloc.c (ext2_free_blocks): Function changed to access disk blocks in a new way. (ext2_new_block): Likewise.
