Changing the stat(2) API to support 64-bit inodes does not require us to simultaneously change the on-disk layout of every filesystem we support to use 64-bit inodes. However, if we want to fully support filesystems with 64-bit inodes (such as FAT32, which currently uses a convoluted hack to map the 64-bit offset of a directory entry into a 32-bit inode), we need to change the API. The ironic thing is that we already have a 64-bit stat(2)... for Linux ABI compatibility. DES -- Dag-Erling Smørgrav - des_at_des.noReceived on Mon Jun 06 2005 - 13:24:41 UTC
