2/7 vfs: reimplement deferred inactive
ClosedPublic

Details

Summary

Previous behavior of leaving VI_OWEINACT vnodes on the active list without a hold count is eliminated. Instead, hold count is kept and inactive processing gets explicitly deferred by setting the VI_DEFINACT flag. The syncer is then responsible for vdrop.

This is taken out of D22995

Do you need to assert that this is not the last vdrop ?
