[Openswan dev] ipsec_kern24.h usage and history?

[Paul Wouters]

Hi,

While tracking down a bug in ipsec_dev_put being undefined, I ended up
chasing this to ipsec_kern24.h. This confused me, because the name
suggests it is for 2.4 kernels only, as does the header in that file saying
this are macros for 2.6 calls. And a check in ipsec_kversion shows:

#if __KERNEL__
# if LINUX_VERSION_CODE <= KERNEL_VERSION(2,6,0)
#  if LINUX_VERSION_CODE >= KERNEL_VERSION(2,4,0) 
#   include "openswan/ipsec_kern24.h"

But if you look at many files in linux/net/ipsec, they end up including
ipsec_kern24.h directly - in fact, they seem to require it for various
macros (including the one I was hunting down, ipsec_dev_put())

Does anyone know the history behind this?

Should this be cleaned up into ipsec_kversion.h?
