From b57ac2c43e66cb4aa76c9d2d0e9e0e04f19cc5a6 Mon Sep 17 00:00:00 2001 From: Jan Kara Date: Wed, 22 Jul 2009 13:17:15 +0200 Subject: ocfs2: Make global quota files blocksize aligned Change i_size of global quota files so that it always remains aligned to block size. This is mainly because the end of quota block may contain checksum (if checksumming is enabled) and it's a bit awkward for it to be "outside" of quota file (and it makes life harder for ocfs2-tools).
