[PATCH] Ext3 xattr credits fix for quotas
From: Andreas Gruenbacher <agruen@suse.de>
The xattr and acl code are not properly reserving credits for quotas.
EXT3_DATA_TRANS_BLOCKS is an overestimate of the credits required including
quotas. Make it a little more tight, and use it in the xattr and acl code
to be quota safe.
