From fef6925cd4c6b564ecff477e07a0fca987542223 Mon Sep 17 00:00:00 2001 From: Jan Kara Date: Tue, 12 Jun 2012 16:20:40 +0200 Subject: ocfs2: Convert to new freezing mechanism Protect ocfs2_page_mkwrite() and ocfs2_file_aio_write() using the new freeze protection. We also protect several ioctl entry points which were missing the protection. Finally, we add freeze protection to the journaling mechanism so that iput() of unlinked inode cannot modify a frozen filesystem.
