I'm attaching a patch that you apparently need to apply to compile enbd
2.4.24 w/ kernel 2.2.*; things from the kernel 2.4.* like bh_kmap and
mark_buffer_protected are not available in kernels 2.2.*, but use the
functionality available in 2.2.* and thus can be defined; also, as I
reported earlier, some plug_device_fn stuff was left outside
"#if LINUX_VERSION_CODE < KERNEL_VERSION(2,3,30)" statement.

Once the patch has been applied, everything compiles and seems to be
working, although I haven't tested it extensively yet.

best,

-Leonid

P.S. I'm using kernel 2.2.17/SMP, RedHat's "2.2.17-14enterprise" built.
