Charles The test for 2.6.x in patch-ker.sh fails with kernels 3 and up. A fix is trivial but as I am not profficient with git and am discouraged from fixing it directly. Also, 2.6.39 has removed the .get_sb field and only supports the .mount field in file_system_type struct. I attach a non-git patch that seems to work ok. It tests for kernel version >= 2.6.39 but as this probably applies to previous kernels it may be better to #define USE_MOUNT_FIELD conditional of some previous kernel threshold and use that instead.
