[f2fs-dev] [PATCH] f2fs: change compr_blocks of superblock info to 64bit

[Daeho Jeong <daeho43@gmail.com>]

From: Daeho Jeong <daehojeong@google.com>

Current compr_blocks of superblock info is not 64bit value. We are
accumulating each i_compr_blocks count of inodes to this value and
those are 64bit values. So, need to change this to 64bit value.
