Revision a835429cda91621fca915d80672a157b47738afb authored by Sean Christopherson on 25 March 2021, 20:01:17 UTC, committed by Paolo Bonzini on 30 March 2021, 17:19:55 UTC
When flushing a range of GFNs across multiple roots, ensure any pending flush from a previous root is honored before yielding while walking the tables of the current root. Note, kvm_tdp_mmu_zap_gfn_range() now intentionally overwrites its local "flush" with the result to avoid redundant flushes. zap_gfn_range() preserves and return the incoming "flush", unless of course the flush was performed prior to yielding and no new flush was triggered.
