How do you know this is curthread here?

It gets assigned here

Before commit a92a971bbb94ad5b, vget() would assert that td == curthread.

In the above commit, the thread argument was dropped from vget().

vget() was the last consumer of the thread argument in ffs_reload(); curthread or the thread argument isn't referenced at all in ffs_reload().

Then this looks good to me... I'd get kib or kirk to bless
