Subject: export atomic64_t into /proc/sys/
Date: Tue, 16 Aug 2011 22:44:42 +0800	[thread overview]
Message-ID: <000301cc5c23$0ce61dc0$26b25940$@gmail.com> (raw)

Hello everyone,

         In my module, there is an atomic64_t counter for something , such
as packets received by Ethernet card.

         What I want to do is to export this atomic64_t number into
/proc/sys/net/ipv4/. The question is atomic64_t 

is an 64-bit long integer which is not support by kernel's default
proc_handlers like proc_dointvec(), proc_dointvec_minmax() and so on.

         So, Do I have to implement one proc_handler to handle this 64-bit
integer?

         Or you have some better ideas?

 

         Any reply will be appreciated and Thanks in advanced.
