I need to get snapshots working with 2.4.1. I've tried using just the
straight LVM that comes with the kernel and I have tried applying the
patches as described above. I either case, when I uncomment:

#define LVM_VFS_ENHANCEMENT 

in drivers/md/lvm.c to enable the hooks for snapshots the compile fails:

drivers/md/mddev.o: In function `lvm_do_lv_create':
drivers/md/mddev.o(.text+0x11bdb): undefined reference to `fsync_dev_lockfs'
drivers/md/mddev.o(.text+0x11c90): undefined reference to `unlockfs'

Can someone point out what else I am missing?
