I would like to maintain some filesystem metadata as an on-disk datastructure that can be read and written to from within the filesystem module. I know file access from within the kernel is a bad idea; what is the recommended alternative for this?You can try to have a reserved inode and use that.
That is what I was trying to do, but I can't find any documentation on how to read/write to it. Could you point me towards some docs or examples? martin
