Since fsstress and src/t_immutable don't need attr/xattr.h, just remove
<attr/xattr.h>  check.

Looks like we could remove the check for getxattr too.

AC_DEFUN([AC_PACKAGE_NEED_GETXATTR_LIBATTR],
...
You're right. I will resend the patch.
It's a straightforward change, I can fix it on commit, no need to resend :)
Sorry, but I have to say we have missed AC_PACKAGE_NEED_GETXATTR_LIBATTR
in configure.ac. So need I send a separate fix to remove it?
Hi FengQi, Eryu

Building src/ and ltp/ still failed due to undefined LIBATTR variable even if we remove
AC_PACKAGE_NEED_GETXATTR_LIBATTR  from configure.ac.

AC_PACKAGE_NEED_GETXATTR_LIBATTR is to check if attr library instead of getxattr is available,
and building src/ and ltp/ depends on attr library.

It is sane to keep this function(AC_DEFUN([AC_PACKAGE_NEED_GETXATTR_LIBATTR]).

Thanks,
Xiao Yang
