From 81c81f5421cb9b85e793c591595a0a4d6ee04e99 Mon Sep 17 00:00:00 2001

Subject: [PATCH] libext2fs: change getpagesize to sysconf

Newer versions of glibc no longer export the getpagesize() prototype when
using recent versions of POSIX (_XOPEN_SOURCE).  So building tdb.c gives
use implicit function declaration warnings.  Fix the issue by using the
portable sysconf() function which returns the same answer.
