From f948dd76dde021c050c7c35720dc066a8b9a5e35 Mon Sep 17 00:00:00 2001 From: Dave Chinner Date: Wed, 3 Apr 2013 16:11:19 +1100 Subject: xfs: add CRC checks to remote symlinks Add a header to the remote symlink block, containing location and owner information, as well as CRCs and LSN fields. This requires verifiers to be added to the remote symlink buffers for CRC enabled filesystems. This also fixes a bug reading multiple block symlinks, where the second block overwrites the first block when copying out the link name.
