Hi everyone
Since any user level code can't be called from kernel level code i
need to provide a way to let my fs LKM asks my user level FS engine
for underlying fs services and the FS engine responde to the LKM that
respondes in it's turn to the client
after some googling i found that such a solution is done by CODA fs by
means of a dummy character device .. what are the things should i know
(besides the VFS) to implement such a dummy character device any
pointers will be helpful
second .. is there any other way rather than the mentioned above
solves the user level/kernel level interaction problem ? (i just need
a memory space and synchronisaion object that both can be used by the
user and the kernel code)
Thanks in advance
MHD.
Sorry .. i've just found something called netlink and i think this is
what am looking for right ? .. i'll read it's manuals now
sorry for inconvenience
MHD
