...tried it. Both on the new box (2.4.21-7um) and on my laptop (about three csets shy of the v2.6.0-test6 tag). Both bombed out in the journal. My uml provider forwarded this from the uml console: Assertion failure in journal_revoke() at revoke.c:329: "!(__builtin_constant_p(BH_Revoked) ? constant_test_bit((BH_Revoked),(&bh->b_state)) : variable_test_bit((BH_Revoked),(&bh->b_state)))" Kernel panic: kernel BUG at revoke.c:329! I was able to use dmesg(1) to see the prink() the laptop generated but was unable to copy it down. It did reference journal... and var was remounted ro, so...

Hi: This series tries to fix various issues of vhost: - Patch 1 adds a missing write barrier between used idx updating and logging. - Patch 2-3 brings back the protection of device IOTLB through vq mutex, this fixes possible use after free in device IOTLB entries. - Patch 4 fixes the diry page logging when device IOTLB is enabled. We should done through GPA instead of GIOVA, this was done
