This series changes the way of selecting what metadata overlap checks to perform from (currently) using a macro to using a variable contained in BDRVQcowState which can be configured at runtime through several command line options.
Although this does not seem necessary anymore regarding performance (because I could not find any performance hits using cached overlap checks), it seems cleaner to me this way. This series depends on: - qcow2: Correct snapshots size for overlap check Max Reitz (6): qcow2: Use negated overflow check mask qcow2: Make overlap check mask variable qcow2: Add overlap-check options qcow2: Array assigning options to OL check bits qcow2: Add more overlap check bitmask macros qcow2: Evaluate overlap check options block/qcow2-cache.c | 8 ++--- block/qcow2-cluster.c | 16 ++++----- block/qcow2-refcount.c | 22 ++++++------ block/qcow2-snapshot.c | 12 +++---- block/qcow2.c | 93 +++++++++++++++++++++++++++++++++++++++++++++++--- block/qcow2.h | 30 ++++++++++++---- 6 files changed, 137 insertions(+), 44 deletions(-) -- 1.8.3.1
