-Date: Wed, 27 Jan 2021 09:42:15 -0300
-Subject: [PATCH] scrub should work for symlinks pointing to block devices
-
-In [1] (add -L option to avoid scrubbing symlink target [Tim
-Boronczyk]), scrub introduced a -L (--no-link) option so that it would
-not scrub the target, if it was a link and this new option was set.
-
-A side-effect of that change is that scrub stopped working for links
-pointing to a block device, whereas it would still work for links
-pointing to regular files -- it is not clear from the commit changelog
-and the added documentation for this new option that this was an
-intended change.
-
-In this commit we fix this regression, and scrub works again for links
-pointing to block devices. -L/--no-link option also works for these
-links.
