Subject: (wipename): Work even if the directory is writeable
X-Git-Tag: v5.3.0~819
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=1def589bea0974dc92183b99efc18545c8f88c33;p=thirdparty%2Fcoreutils.git

(wipename): Work even if the directory is writeable
and not readable.  Prefer write access, since this should work
better with fdatasync.
