Extended file stat: Splitting file- and fs-specific info?

[Roland McGrath]

POSIX specifies st_blksize thusly: "A file system-specific preferred I/O
block size for this object. In some file system types, this may vary from
file to file."

Since there is only one available to POSIX applications, it should map to
the one that's described as "preferred IO size for general usage".


Thanks,
Roland
