| |
i_blkbits stores the log n of the blocksize; there is no reason for it to take more than 16 bits, so change it to be a short and put it next to i_mode.
i_version and i_dnotify_mask need to be 32 bits, but there is no reason for them to be 64-bit values on 64-bit architectures, so make them be unsigned int's instead of unsigned long's.
