I am writing a 2.4.x device driver LNVRM I was going to use proc for debug and interface But proc dose not support report files because it dose not have OPEN and RELASE functions
My report files work like this 1. OPEN Memory is allocated and status information is loaded into the memory 2. READ Normal read of the memory (report) 5. REALISE The report memory is freed
so now I want my driver when is starts to make an mount point in /proc/lnvrm and then auto mount my FS also my FS will have whatever status info and a fixed file in it called device witch will be a char device node witch will point to my auto assigned mayor / minor number I do not want to use 2.4.x vdev as this way just dose it all in one
I have done proc code before but run into lots of brick wills I guest I need to know 1. how do you make a mount point in /proc ? 2. how do you auto mount that point ? 3 how do you make a device node in proc ? (I wont use this but it is interesting to me)
also I have written a read / write FS before but this was mainly by locking at outer peoples work is there some relay good info on writing a linux FS for free download ? (no I don't have any CC's)
thank you
