[Qemu-devel] [PATCH 0/6] Configure metadata overlap checks at runtime

[Max Reitz]

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
