Can read_proc still be executing when remove_proc_entry returns?
In my driver [*] I allocate some data and create a proc entry using create_proc_entry. My read method reads from my allocated data. When shutting down, I call remove_proc_entry and immediately free the data. If some call to read_proc is still executing at this point then it will be accessing freed memory. Can this happen? I've been rummaging around in fs/proc to see what prevents it, but didn't find anything yet.
Thanks a lot,
Duncan.
[*] Actually it's the ATM layer that does all this (net/atm); my driver uses that layer. - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
