[0/3] KVM: selftests: Small fixes for dirty_log_perf_test

Message

David Matlack Sept. 15, 2021, 9:30 p.m. UTC

This series fixes 2 bugs in dirty_log_perf_test:
 - Incorrect interleaving of help messages for -s and -x (patch 2)
 - Buffer overflow when using multiple slots (patch 3)

Both bugs were introduced by commit 609e6202ea5f ("KVM: selftests:
Support multiple slots in dirty_log_perf_test").

Patch 1 is a small tangentially related cleanup to use a consistent
flag for the backing source across all selftests.

David Matlack (3):
  KVM: selftests: Change backing_src flag to -s in demand_paging_test
  KVM: selftests: Refactor help message for -s backing_src
  KVM: selftests: Fix dirty bitmap offset calculation
