Hi Andrew,
this fixes the 2G limit on ramfs

Why don't we change the default in alloc_super() instead?
We should not default to "lame" :)

we default to "lame" to protect the lame filesystems from
malfunctioning ;), this was extremely intentional in the early days, now
less but it's still intentional. We may change that someday but
defaulting to safe when there's no downside doesn't sound that urgent to
change.

yep - fixed this for RHEL3 half a year ago but forgot about it. It works
well, people are using multi-GB ramfs instances without problems.
