I have a small patch against 1.3.62, which fixes the (known) if_slip.h
problem, and also:
- Add symbol 'scsi_mark_host_bus_reset' to scsi_syms. This one is used
by 'BusLogic.c', when built as a module.
- Add '#include <linux/mm.h>' (probably not the right place) to
fatfs_syms.c and msdosfs_syms.c, so genksyms can find all structs
when building with CONFIG_MODVERSIONS.
- This one is a more important one:
When building 'rarp.o' as module, the module should do an
MOD_INC_USE_COUNT for every address it has to serve, otherwise it
will be subject to autocleaning, which looses the addresses.
MOD_DEC_USE_COUNT is called for every freed address.
With all this, it is possible (and advisable, IMHO) to have af_inet.c
try to load "rarp", when it had not been installed, and CONFIG_KERNELD
is set.
I don't know, if this is the right place to send patches, so please
tell me the correct address if not.
Here comes the diff against 1.3.62:
(hope this is useful, Eddie)
