ovl: fix format of setxattr debug
Format has a typo: it was meant to be "%.*s", not "%*s". But at some point callers grew nonprintable values as well, so use "%*pE" instead with a maximized length. Reported-by: Amir Goldstein <amir73il@gmail.com> Signed-off-by: Miklos Szeredi <mszeredi@redhat.com> Fixes: 3a1e819b4e80 ("ovl: store file handle of lower inode on copy up") Cc: <stable@vger.kernel.org> # v4.12
