Hello Everybody.
I have a problem with system call.
Well , I'm trying to create a system call that blocks(for read and write) an archive(inode) or a partition(for read and write).
But I'm not finding a function where I can deactivate this in the inode.
Well , I would like to know if someone know or can help me find this function or give me a material where I can solve my problem.

Thank you!
