Subject: vfs_streams_xattr: invalidate stat info if xattr was not found
X-Git-Tag: samba-4.5.13~13
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=da22be9167a342e2edfbdb49a9b9d34e5bde9b66;p=thirdparty%2Fsamba.git

vfs_streams_xattr: invalidate stat info if xattr was not found

We stat the basefile so we leave valid stat info from the base file
behind, even though the xattr for the stream was not there.
