Revision 5f3ef64f4da1c587cdcfaaac72311225b7df094c authored by Tyler Hicks on 14 October 2009, 21:18:27 UTC, committed by Tyler Hicks on 20 January 2010, 04:32:07 UTC
When truncating inodes in the lower filesystem, eCryptfs directly invoked vmtruncate(). As Christoph Hellwig pointed out, vmtruncate() is a filesystem helper function, but filesystems may need to do more than just a call to vmtruncate(). This patch moves the lower inode truncation out of ecryptfs_truncate() and renames the function to truncate_upper(). truncate_upper() updates an iattr for the lower inode to indicate if the lower inode needs to be truncated upon return. ecryptfs_setattr() then calls notify_change(), using the updated iattr for the lower inode, to complete the truncation. For eCryptfs functions needing to truncate, ecryptfs_truncate() is reintroduced as a simple way to truncate the upper inode to a specified size and then truncate the lower inode accordingly. https://bugs.launchpad.net/bugs/451368 Reported-by: Christoph Hellwig <hch@lst.de> Acked-by: Dustin Kirkland <kirkland@canonical.com> Cc: ecryptfs-devel@lists.launchpad.net Cc: linux-fsdevel@vger.kernel.org Signed-off-by: Tyler Hicks <tyhicks@linux.vnet.ibm.com>
