Subject: xfs_scrub: load and unload libicu properly
X-Git-Tag: v5.11.0-rc1~22
X-Git-Url: http://git.ipfire.org/?p=thirdparty%2Fxfsprogs-dev.git;a=commitdiff_plain;h=ff8717e52b7364625acb942238cb29d93cbbe25b

xfs_scrub: load and unload libicu properly

Make sure we actually load and unload libicu properly.  This isn't
strictly required since the library can bootstrap itself, but unloading
means fewer things for valgrind to complain about.
