One implementation question, one future question. Would /sys/kernel/net be a little better? or /sys/kernel/sunrpc ? Do you have a plan to integrate support for fs_locations to probe servers for alternate IP addresses? Would that be a userspace utility that would plug values into this new /sys API? > Anna > > > Anna Schumaker (7): > net: Add a /sys/net directory to sysfs > sunrpc: Create a sunrpc directory under /sys/net/ > sunrpc: Create a net/ subdirectory in the sunrpc sysfs > sunrpc: Create per-rpc_clnt sysfs kobjects > sunrpc: Create a per-rpc_clnt file for managing the IP address > sunrpc: Prepare xs_connect() for taking NULL tasks > sunrpc: Connect to a new IP address provided by the user > > include/linux/sunrpc/clnt.h | 1 + > include/net/sock.h | 4 + > net/socket.c | 8 ++ > net/sunrpc/Makefile | 2 +- > net/sunrpc/clnt.c | 5 ++ > net/sunrpc/sunrpc_syms.c | 8 ++ > net/sunrpc/sysfs.c | 160 ++++++++++++++++++++++++++++++++++++ > net/sunrpc/sysfs.h | 22 +++++ > net/sunrpc/xprtsock.c | 3 +- > 9 files changed, 211 insertions(+), 2 deletions(-) > create mode 100644 net/sunrpc/sysfs.c > create mode 100644 net/sunrpc/sysfs.h > > -- > 2.29.2 > -- Chuck Lever
