Subject: xfs_scrub: allow developers to force repairs
X-Git-Tag: v4.18.0-rc1~16
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=7a9d1ac4b042a99f14f5535e945699c2d0a48882;p=thirdparty%2Fxfsprogs-dev.git

xfs_scrub: allow developers to force repairs

Now that we have an error injection knob in the kernel to simulate
corruptions, enable it in xfs_scrub so that developers can test all
the repair capabilities.
