This patch series fixes the following problems on 32 bits architecture. o stat64 returns the lower 32 bits of blocks, although userland st_blocks has 64 bits, because i_blocks has only 32 bits. The ioctl with FIOQSIZE has the same problem. o As Dave Kleikamp said, making >2TB file on JFS results in writing an invalid block number to disk inode. The cause is the same as above too. o In generic quota code dquot_transfer(), the file usage is calculated from i_blocks via inode_get_bytes(). If the file is over 2TB, the change of usage is less than expected. The cause is the same as above too. o As Trond Myklebust said, statfs64's entries related to blocks are invalid on statfs64 for a network filesystem which has more than 2^32-1 blocks with CONFIG_LBD disabled. [PATCH 3/3] We made patches to fix problems that occur when handling a large filesystem and a large file. It was discussed on the mails titled "stat64 for over 2TB file returned invalid st_blocks".
