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.
Ah, I see your point. Well, it's not too late to address this for 6.0,
and it might be a really good idea to think about it now. Is there
anything else that should be bumped along with it?
Not that I know of.
I believe the best way to do this is the way Linux did it: introduce
new *stat64() syscalls and keep the old ones around. #define magic in
<sys/stat.h> will take care of making *stat64() look like *stat().
